Mrs. Mulligan’s Class Ecosystem Presentation

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

Biotic Components The living part of our ecosystem includes the cabbage, pepper, rolypolys, spider, crickets, worms and bacteria. We have some dead leaves in there that used to be alive.

Producers and Consumers

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, rolypolys, doodle bugs Bacteria found in the soil

Food Chain

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 Bacteria breaks down dead animals and nutrients go back into soil Worms break down dead animals

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 rolypolysstay mainly under the rock
