Distinguish between intraspecific and interspecific competition. How do they affect species as a form of environmental resistance?
What will be an ideal response?
Interspecific competition is competition between species, while intraspecific competition is competition within a species. Interspecific competition occurs when ecological niches overlap. Intraspecific competition occurs because members of the same species are competing for the same resources. Intraspecific and interspecific competition are forms of environmental resistance that limit a population size because these types of competition result from density-dependent biotic and abiotic factors that are necessary for survival.
