In Mrs. Rose and Ms. D'Agostino's AP/Honors Environmental class, students were tasked with building an ecosystem column. We had a great opportunity to talk with seniors Nate LaChance and Austin Burrows who described each layer for us. There are three levels to the ecosystem:
Level 1: The terrestrial layer, which encompass plants and soil.
Level 2: The decomposition layer, which is filled with decomposed fruit, bugs, coffee grounds, leaves, and bugs (fruit flies)
Level 3: The aquatic layer, which has a living fish, plants, and two snails that eat the plants, which releases nitrogen which releases into the other two layers. In about two-three weeks the ecosystem will be self sufficient and you will no longer need to feed the fish.
