Dirt...it's what's for dinner


Earlier in the year we talked about the food chain and how energy is transfered through ecosystems. We learned that a food chain starts with the producers (organisms that can make their own food) and then how that energy can then be transfered to the herbivores, omnivores, carnivores, and finally the decomposers. Well, if it is true that the food chain begins with the producers then the most vital aspect of that chain must be the ground in which those organisms grow. We don't often give respect and appreciation for the dirt that is one of the most significant components of our ecosystem.

Page 1: Soil is made up of decaying organic matter called humus, soil also has air and water in it, and this allows organisms like earthworms to live in soil.

Page 2: Soil is home to many different living things, scientist all over the world work together but speak different languages so they use the earthworm's Latin name (Lumbricus terrestrits), and there are billions of earthworms around the world.

Page 3: The soil ecosystem has its own food web, The soil food web is different from the above ground food web because they have different sources of energy.

1. Soil ecology
(a).Soil covers most of the land on earth from parks to under our houses.
(b). Soil is made up of things like organisms, ants, small animals, and earthworms.
(c). Because of all the pollution and global warming we are causing it is damaging the soil in major ways.

2.What is Soil
(a) Soil has a lot of thing in it like rocks, water, minerals, air. and humus.
(b) There are small organisms, earthworms, bacteria, small plants, fungi, small animals ect... in soil that need the nutrition of thing like the ones listed above.
(c) all the things in the soil create an ecosystem.

3, interactions between species
(a) one of the main interactions between species another type of species interaction is the food web which can be one species eating another spices (or one of there own.)
or the food chain (sun makes energy for plants to grow, herbivores eat plants, then carnivores eat the herbivores, then when they die the decomposers eat there dead bodies.
(b) unlike the above ground food chain whose energy comes from the sun in the underground food chain the energy comes from a dying organic matter whose name is detritus
(c)This matter gives food to things like fungi and bacteria who when done eating rerelease the food back into the earth

4. Our research
(a) when our temp. changes to does the temp. in the soil one of the major things that can change the soil is a rainstorm.
(b)the changes in the soil change the organisms to which changes the routine and the decomposing speed.
(c) So because of these facts scientists must re-monitor and re-monitor the soil in the same place because of its rapid changes.

5. Soil organisms and species
(a)there al billions upon billions of earthworms (Lumbricus terrestris) on earth, yes they are part of one species but they are all there own organism
(b)there are all kinds of species in the earths soil form single-celled things like algae to small plants and vertebrates.
(c)inside the soil environments there are so many biodiversity's that soil is considered to be one of the most diverse places on earth.

6. changes in time and place
(a)soil organisms are so small compared to us that they only take up a few very tiny millimeters of the earth and are invisible to toe naked eye.
(b) Any damages that happen to the soil affect the "lives" of organisms and the environments inside the earth.
(c) some of the things that may damage soil are pollution, erosion, people ect.

1.)~Soil Ecology~
Humans, animals, and incests all live on or in soil. Soil grows are food, its what we eat. Because of pollination it is destroying the soil, giving the soil bad reactions.

2.)~What is soil?
soil is made out of broken down and decaying rock, and humas. Having air, water makes it possible for plants, and other organisms to grow. To understand this process, scientist are always on observation.

3.)~How do we study soil?
Scientist who study soil are called soil ecologists. The scientist have to do many experiments. Scientist take samples to resherch soil.

4.)~Soil Organisms and Species
Scientist are all come from all over the world, and they don't all speak the same language, so when they are naming the species they have to say their scientific name. It is important for scientist to measure the health and life of an ecosystem.

5.)~Biodiversity
There is a lot of diversity in the soil and fewersoil ecologists. There are so many species that haven't yet been identified. Even thought these species have not all been named, scientist try to find out what their purpose is.

6.)~Interactions between Species
One of the most common interactions between species is the food web, and had it goes from one animal to the next. When the animals die, bacteria helps decompose it. Some bacteria is food to other animals

Soil ecology

1. Soil is home to millions of tiny soil organisms.

2. soil is an important resource for growing food.

3. Soil covers almost all of earths land.

What is soil?

1. Soil is a mixture of broken rocks and minerals, living organisms and decaying organic matter called humus.

2. One way to study soil is called surveying, surveying is when scientists watch a small part of natural area and make observations in detail.

3. Scientists study the soil ecosystem so that they can understood how organisms relate to each other and to the environment.

Soil organisms

1. Many species of soil organisms have not been identified.

2. An important measure of health in an ecosystem such as soil is the variety of species that live int eh ecosystem.

3. Because many scientists work together and all speak different languages they cannot name an earthworm by its common name so they use latin to name bugs scientifically.

interactions

1. Herbivores are plant eating animals

2. erosion is a natural process int he soil ecosystem that occurs when water washes away soil.

3. Decomposition happens when soul organisms such as bacteria and fungi break down organic matter.

Changes

1. soil organisms are much smaller than we are, there world takes place in a tiny few millimeters across area.

2. Damage tot he soil has a tremendous impact on the soil ecosystem and the organisms that live in it.

3. when soil is lost the organisms that live within it suffer.

Our research

1. Sensor networks are able to continually measure the temperature and moisture of soil

2. soil temperature varies daily just like our weather temperature.

3. Moisture in the soil also changes and the organisms must quickly adapt.

S.E.
when soil changes animals in the soil change.
soil has been changed many ways.
soil degradation is a big problem.

W.I.S.
decaying organic matter is called humus.
there are many ways to study soil.
a new way to study soil is sensor network.

S.O./S.
there are many kinds of earthworms.

lots of soil animals have exoskeletons.

I.
the soil food web is different than ours.
soil food webs are very complex.
humus is very important.

C.
good soil is endangered.
the biodiversity of soil is endangered.
people are the ones damaging soil.

R.
the soil's temperature and moisture are very important facts.
the temperature and moisture of soil varies.
sensor network will heip fix soil.

Soil Ecology
Soil covers most of the earths land. When you walk in the woods, parks and in the backyard of a house you will see soil. Also soil is the surface for building and house. Lastly soil is used for planting plants,trees and agriculture.

What is soil?
A mixture of broken rocks and minerals, living organisms, and organic matter. Soil is also is made up of air and water. Without air and water organisms wouldn’t be able to survive. If it weren’t for the materials of air, water and organic matter plants, bacteria, fungi and small animals like, earthworms and insects wouldn’t exist in the soil.

Soil organisms
When their is a living thing it is known as an organism. For example an earthworm. And when it is a group of the same type of organism it is known as a species.

Interactions
One type of interaction between two species is who eats who. The above ground species get their energy comes from the sun because sun grows grass which helps feed the herbivores. And the herbivores provides food for the carnivores. For example deer. Underground food source for bacteria and fungi is decaying organic matter.

Changes
Change can happen through varies of temperature through the day and with season. Also a rainstorm can change the soil moisture in just a few minutes. And pollution changes the environment into being unhealthy for natural resources.

Our Research
Organisms in the soil affect and are affected by the surrounding of an environment. And soil throughout the day change in soil moisture and the temperature.

1.soil covers the earth.
soil is an important resource.
we have changed soil in many ways over the years but now we are destroying it with our chemicals.

2.soil is a mixture of rocks, minerals and living organisms.
soil ecologists spend months studying like a plot of land.
scientists collect samples of soil for testing.

3. soil is home to many small and even large organisms.
organisms all have their own latin name.
the majority of soil organisms are undefined so far.

4.the soil food web is alot more diverse than others.
organic matter feeds the whole food web.

5. soil organisms are much smaller than us.
their world takes place in spots maybe only 1 millimeter long.
damage to the soil impacts its life.

6. like all creatures soil organisms affect and are affected by their surroundings.
we have tools that let us track soil change.
this helps us understand our impact on soil.

1. Species means all organisms can reproduce

2. An important measure of the health of an ecosystem is the variety of species that live in that ecosystem

3. Biodiversity is the number of species in an ecosystem

Page 4
1. Understanding interactions between species is just as understanding the species themselves

2. The most important types of interactions between species is which species eat other species

3. Detritus provides food for decomposer's such as bacteria and fungi, and when bacteria and fungi feed on detritus, they release nutrients back into the soil.

1. The lives of soil organisms take place in miniature, in areas just a few millimeters across

2. Soil temperature changes daily with each season.

3. Soil organisms and their environment are interconnected.

Page 6
1. Soil organisms affect, and are affected by, their surrounding environment.

2. A sudden rainstorm can drastically change soil in a matter of minutes.

3. Temperature and moisture levels in the soil affect the activity of or all organisms, thereby affecting the rate of soil decomposition.

WHAT IS SOIL?

 Soil is broken rocks, minerals, and humus.
 Organisms in soil need air and water to survive.
 All living things form the soil ecosystem.

SOIL ORGANISMS

 The health of the soil is provided by the many organisms in it.
 Soil has most of the best biodiversity.
 The scientific name for the earthworm Lumbricus terrestris.

INTERACTION

 One of the most interaction between species is which ones eat each other.
 The source of energy is the sun
 The food web is different for species underground.

CHANGES

 Soil can change greatly in time.
 Damaged soil is a big impact on the organisms.
 Both natural and human occurrence may damage the soil.

OUR RESEARCH

Soil Ecology

1. Soil covers most of the Earth's land.
2. Soil has many organisms living in it.
3. We are changing the soil with pollution.

What is soil?

1. Soil is a mixture of broken rocks and minerals, living organisms, and decaying organic matter called humus.
2. Scientists collect soil or organisms in the field and bring them back to the lab to do sampleing.
3. All the living things in the soil, plus essential materials that these organisms use to survive, form the soil ecosystem.

Soil Organisms.

1. There are billions of earthworms in the world - each earthworm is an individual organism, but they are all members of the earthworm species
2. An important measure of the health of an ecosystem such as soil is the variety of species that live in that ecosystem.
3. The many species that live in the soil range in size from tiny one celled bacteria, algae, fungi, and protozoa to more complex organisms like earthworms, insects, small vertebrates, and plants.

Interactions

1. One of the most important types of interactions between species is which species eat other species.
2. The sun helps grass and plants grow, providing food for herbivores like deer.
3. The first major difference between the above-ground food web and the soil food web is that the soil food web has a different source of energy.

Changes

1. A sudden rainstorm can drastically change soil moisture in just a few minutes.
2. Many different forces in the environment may damage soil, both natural and caused by people.
3. When too much erosion occurs in a specific area, for example, the water washes away many of the nutrients in the soil.

The bacteria in the soil need oxygen and water to maintain life.
Soil covers the entire earth.
Soil is the broken down rock and mineral decaying matter and living organisms.
There are billions of earthworms on the earth.
As human change the soil every day sometime causes long term damage.
Scientist who studs the soil ecosystem is called soil ecologists.
Once soil is damage it very hard to replace we damage the soil by pollution, erosion, and other degradation soil.
The underground food web the main source of energy is matter.
It very important to understand the soil organism temperature and level of moisture
A sudden rain storm can change the temperature and the moisture of the soil affecting all living soil organisms and actives.
With surveying scientist make and observe a small piece of the earth and watch for change in the moisture and temperature.
The soil temperature and moisture change from place to place depending on the environment the soil ecologists must monitor it closely.
When damage to soil very a serious impact on soil organism life and the soil ecosystem.
There are so many soil species not all of them have been identify.
