Answer

Brief Explanations:

Marsh snails feed on phytoplankton. With phytoplankton depletion due to pollution, marsh snails lose a food source, so their population will decrease. Painted turtles feed on marsh snails. As marsh snail population drops, painted turtles have less food, causing their population to also decrease.

Answer:

D. The populations of marsh snails and painted turtles will decrease.
