Pre Assessment

What is the definition of carrying capacity in ecology?

• The total number of individuals of a species in an ecosystem.

• The maximum population size of a species that an ecosystem can sustain indefinitely.

• The number of predators in an ecosystem that control the prey population.

• The diversity of species within an ecosystem.

What are limiting factors in an ecosystem?

• Factors that promote unrestricted population growth in a species.

• Factors that have no effect on population size in an ecosystem.

• Factors that limit the growth of a population in an ecosystem.

• Factors that determine the carrying capacity of an ecosystem.
