Abiotic ComponentsThe non-living parts of our ecosystem includes the light, water soil and rocks. The temperature is kept at room temperature
Biotic ComponentsThe 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.
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.
Bacteria found in the soil Isopods (a.k.a. pill bugs, sow bugs, roly polys, doodle bugs
Earthworms
InteractionsPlants 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
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
