The correct answers are:

a. 2. decrease.

b. 2. decrease.

Since the phytoplankton is at the bottom of the food chain in this situation, and it is the one that is the most affected by the pollution, all the species directly and indirectly connected to it will suffer as well.

The numbers of the marsh snails will significantly decrease because they will lose their primary food source. As a chain reaction, as the number of marsh snails decreases, the painted turtles will lose their own prime food source, sot heir numbers will decrease significantly as well.

Answer: Both of them would be decrease hope this helped!
