Parland’s alligator population has been declining in recent years, primarily because of hunting. Alligators prey heavily on a sp
IRISSAK [1]

Answer:

(C) The main predator of these fish is another species of fish on which alligators also prey.

Explanation:

The ecosystems are complex systems, and removing one species of them, always has a chain reaction and affects the population of the other species, be it in a positive or negative manner. In this case, the alligators prey upon fish, multiple different species. The alligators though have been removed from the ecosystem, thus the apex predator exists no more. This has opened up the top predator niche in the food chain in this particular ecosystem. The predatory fish species had no predators of its own, so its population increased, thus it needed more food, and that food was obtained by hunting the other fish species, resulting in a decline in the population of the other species of fish. Only when the carrying capacity is reached in the ecosystem for the predatory fish, the population of the other fish will stop declining.

As the minnow population increases in size, how will its rate of growth affect its population density?
