Biology 5.2 Factors Affecting Population Growth

Acting separately or together, ___ determine the carrying capacity of an environment for a species.

• symbiosis

• limiting factors

• densities

• distributions

These types of limiting factors operate strongly when the number of organisms per unit area is higher.

• density dependent limiting factors

• density independent limiting factors

• human impacts

• exponential growth
