Question

if a population of deer exceeds its carrying capacity, it is likely that the
population will crash
population will become extinct.
carrying capacity will increase
birth rate will increase

Explanation:

Carrying capacity is the maximum population size an environment can sustain. When a population exceeds it, resources become scarce. This leads to increased competition, higher mortality, and a population crash. The population won't necessarily become extinct as some individuals may survive. The carrying capacity is a property of the environment and won't increase just because the population exceeds it. With resource - scarcity, the birth rate is likely to decrease rather than increase.

Answer:

A. population will crash
