Question

which of the following would likely result if herons were removed from the ecosystem? choose 2 answers: a the pond snail population would increase. b the sunfish and bass populations would increase. c the sunfish population would decrease. d the pond snail population would decrease.

Explanation:

In an ecosystem, herons are predators. If herons are removed, the populations of their prey will likely increase. Herons often prey on both pond - snails and sunfish/bass. So, the populations of pond - snails and sunfish/bass would likely increase as there is less predation pressure.

Answer:

A. The pond snail population would increase.
B. The sunfish and bass populations would increase.
