Mrs. Mulligan’s Class Ecosystem Presentation
The Environment The non-living parts of our ecosystem includes the light, water soil and rocks. The temperature is kept at room temperature
Living Things 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.
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 Energy flows in our ecosystem as shown in the diagram below
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
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 rolypolys stay mainly under the rock
