Park officials needed to repair the old mill dam in a state park and so had to drain the pond behind,killing all the animals and many of the plants in the water.After the pond reformed and many years passed,a certain species of fish established itself in the pond and remained there for more than 400 years.Which most directly describes the role of that type of fish?

Question

Quizplus · Accepted Answer

A climax species is a species that remains in an ecosystem for an extended period of time and is indicative of a stable, mature ecosystem. The fact that the fish established itself and remained in the pond for over 400 years suggests that it is a climax species. A pioneer species is a species that is one of the first to colonize a newly formed or disturbed area, which does not fit the description of the fish in this scenario. Producers are organisms that produce organic matter through photosynthesis, which does not apply to fish. Invaders suggest an invasive species, which may not be accurate in this scenario.
