Question

ecosystems need time to re - balance after being disturbed. which of the following reasons does not explain the time needed for the rivers and lake on astakos iv to re - balance after installing the filter?
a) carrying capacities of species are related by trophic interactions
b) feedbacks occur between abiotic and biotic components of an ecosystem
c) photosynthetic organisms capture sunlight for only a part of each day
d) organisms need time to grow and reproduce

Explanation:

a) Trophic interactions can affect re - balancing as they determine species population limits. b) Abiotic - biotic feedbacks are crucial for ecosystem stability and re - balancing. d) Growth and reproduction time of organisms are factors in ecosystem re - balancing. However, c) photosynthetic organisms capturing sunlight for part of the day is a normal daily process and not a reason for the time needed to re - balance after a filter installation.

Answer:

C. Photosynthetic organisms capture sunlight for only a part of each day
