Question

several factors prevented the ecosystem from collapsing when phytoyeaston was limited by the filter. which of these factors did not contribute? a) the presence of a large apex predator b) the decision by humans to restore flow to the stream c) the presence of another primary producer d) the ability of consumers to forage away from the lake

Explanation:

A large apex predator typically preys on higher - level consumers and can disrupt the ecosystem balance rather than prevent collapse when a primary producer like phytoyeaston is limited. Restoring stream flow can bring in nutrients and organisms, another primary producer can replace the lost productivity, and consumers foraging away can reduce pressure on the local ecosystem.

Answer:

a) The presence of a large apex predator
