Answer:
Correct options are
a) They act to regulate population growth.
b) They can affect birth rates or death rates
c) One example would be intraspecific competition for resources.
Explanation:
Population growth rates can be regulated by the density of a population and hence population regulation is a density-dependent process. Density-dependent factors include disease, competition, and predation.
The higher the population density, the higher is the mortality rate.
Some of the biotic density dependent factors are
a) intra- and interspecific competition
b) reducing population’s rate of growth
c) Individual’s reproductive rate
Hence, the correct options are
So the correct options are
a) They act to regulate population growth.
b) They can affect birth rates or death rates
c) One example would be intraspecific competition for resources.
