I'll be glad to check your answer.

im am having trouble with this question to plz help What determines the carrying capacity of a particular population by an ecosystem?

A.keystone species
B.pioneer species
C.limiting factors
D.renewable resources

Does anybody have the answers to this test or questions???

I believe it is C, but I am not sure

The correct answer is C. limiting factors. Limiting factors are environmental conditions or resources that determine the maximum population size that an ecosystem can sustain. These factors include food availability, water availability, space, shelter, predation, disease, and competition for resources. When any of these factors becomes scarce or reaches a certain threshold, it limits the growth and size of a population, thus determining the carrying capacity of the ecosystem.

To determine the carrying capacity of a particular population in an ecosystem, one would consider these limiting factors and assess their availability and abundance. By studying the interactions between the population and its environment, ecologists can estimate how many individuals can be sustained in a given ecosystem over time.
