Question

which of the following would likely result if algae and aquatic plants were removed from the ecosystem? choose 2 answers: a the insect larva population would decrease. b the bullfrog tadpole and pond snail populations would decrease. c the heron population would increase.

Explanation:

Algae and aquatic plants are primary producers in aquatic ecosystems, serving as food sources for many organisms like bullfrog tadpoles and pond snails. Without them, these herbivorous organisms would lack food, leading to a decrease in their populations. Insect larvae also often rely on these plants directly or indirectly. Heron populations would likely decrease as their prey (which depend on algae and plants) would decline.

Answer:

A. The insect larva population would decrease.
B. The bullfrog tadpole and pond snail populations would decrease.
