Question

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

Explanation:

Algae are primary producers in an ecosystem. Pond snails often feed on algae. Without algae as a food - source, the pond snail population would decrease. Bullfrogs and insect larvae may rely on organisms that feed on algae or are part of the same food - web that is disrupted by the loss of algae, so their populations would also likely decrease.

Answer:

B. The bullfrog and insect larvae populations would decrease.
C. The pond snail population would decrease.
