Mrs. Mulligan’s ClassEcosystem Presentation

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

Living ThingsThe 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.

Producers and ConsumersP

ers

• 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.

DecomposersThese organisms are decomposersIn 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.

Energy flows in our ecosystem as shown in the diagram below

Interactions

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

Worms break down dead animals

Bacteria breaks down dead animals and nutrients go back into soil

The sun is the main source of all energy on Earth. Producers use energy fromthe sun with Carbon Dioxide to make their food.

ObservationsOur 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
