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
