Species Richness of Fish in Lakes

Question

Species richness of fish in lakes:
A) May be related to primary productivity.
B) May be connected to phytoplankton.
C) Is usually highest at shallow depths than intermediate depths.
D) Is usually highest at the bottom of the lake.

Accepted Answer

Species richness of fish in lakes can be related to primary productivity because higher productivity can support a larger number of fish species by providing more resources. It may also be connected to phytoplankton, as they are a key part of the aquatic food web, serving as a primary food source for zooplankton and small fish, which in turn support larger fish species.
