2. The Environment
The non-living parts of our ecosystem includes the light, water soil and rocks. The temperature is kept at room temperature

3. Living Things
The living part of our ecosystem includes the cabbage, pepper, roly polys, spider, crickets, worms and bacteria. We have some dead leaves in there that used to be alive.

4. Producers and Consumers
A producer is an organism that makes its own food. Green plants use sun light and Carbon Dioxide to make food. Plants have chlorophyll which is the substance that makes them green. Plants give off oxygen which can be used by other animals. When another animal eats a plant, some (not all) of the energy from the sun is passed on to the animal.
Consumers
A consumer is an organism that has to get it’s energy by eating something else. Some consumers eat plants. They are called primary consumers. Some consumers eat other consumers. They are called secondary consumers.

6. Decomposers Earthworms These organisms are decomposers
In our ecosystem. When plants and
Animals die, the decomposers eat the
Dead material. Their waste provides rich
Nutrients that go into the soil to help
Plants grow.
Isopods (a.k.a. pill bugs, sow bugs, roly polys, doodle bugs
Bacteria found in the soil

8. Interactions
The sun is the main source of all energy on Earth. Producers use energy from
the sun with Carbon Dioxide to make their food.
Plants give off oxygen which is used by animals. Animals give off carbon dioxide which is used by the plants
Dead leaves are eaten by worms
Worm waste provide nutrients for plants
Bacteria breaks down dead animals and nutrients go back into soil
Worms break down dead animals

9. Observations
Our spider let the crickets crawl over him for a long time then all of a sudden it grabbed one
We put 5 crickets in to start out with but by the next day there was only one.
The pepper plant is growing well but the cabbage plant is starting to turn yellow.
The pepper plant has some holes in it. We think the crickets are eating it.
The roly polys stay mainly under the rock
