Answer:
Explanation:
the Econauts constructed an ecosystem sealed under glass—a biodome. Recently, the group noticed an ominous decrease in the populations of organisms: the ecosystem appeared to be in the process of collapsing. The occupants were safely removed from the biodome, but the cause of the crash is still a mystery.
The econauts buried dead matter below 6 feet and dead animals in bags =
decomposers need oxygen to exist so they couldn't get to the dead matter that deep in the ground or the dead matter in bags.
Decomposers died =
decrease in cellular respiration
decrease in cellular respiration =
less carbon dioxide in the air
The cycle goes on
