Question

what is emphasized by rules of population ecology? populations are unaffected by changes in habitat. populations must constantly migrate to new areas. populations must not exceed the resources available. populations should never compete for resources.

Explanation:

Population ecology studies how populations interact with their environment. One of its key concepts is the carrying - capacity of a habitat, which is the maximum number of individuals a habitat can support with available resources. Populations are limited by available resources and cannot exceed them in the long - term. Populations are affected by habitat changes, they don't have to constantly migrate, and competition for resources is a natural part of population dynamics.

Answer:

Populations must not exceed the resources available.
