Kettle ponds derive from a hole left by a retreating glacier that is subsequently filled with rainwater. A certain region has a series of disconnected kettle ponds, but occasionally heavy rains flood them and create streams. Which type of animal is most likely to be present in this area as a metapopulation?

Options are:

A. a fish

B. an aquatic bird

C. a mosquito

D. a dragonfly

Answer: Fishes

Explanation:

A metapopulation can be defined as a small population that cannot itself make a large population that is stable. Many sub populations are connected intermittently to combine and form a population.

Small population of fishes would have been separated for most of the years and are joined by when floods occur and these populations are connected by kettle ponds.

Rest of the three organism like bird, mosquito and dragon fly cannot be separated so as to form a metapopulation.
