Question

What determines the carrying capacity of an ecosystem? a. the number of different types of organisms in an ecosystem b. the amount of available resources c. the square mileage it encompasses d. the ratio of biotic to abiotic factors

Answer 1

Answer: D

Step-by-step explanation: The maximum population size that an ecosystem can support is called carrying capacity. Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem.
