In 1800, ten horses were released on an island. Over time, the size of the horse population grew and fluctuated.
At what point on the graph is the population of horses at carrying capacity?
The correct answer is (D). The carrying capacity of an environment is the maximum population size of a species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. On the graph provided, point D represents the carrying capacity for the horse population on the island. This is indicated by the leveling off of the population, suggesting that it has reached a stable state that the environment can support without further significant increases or decreases over a period of time.
