Detailed explanation-1: -Intraspecific competition occurs between members of the same species. For example, two male birds of the same species might compete for mates in the same area. This type of competition is a basic factor in natural selection. It leads to the evolution of better adaptations within a species.

Detailed explanation-2: -Two of them, interference competition and exploitation competition, are categorized as real competition. A third form, apparent competition, is not. Interference competition occurs directly between individuals, while exploitation competition and apparent competition occur indirectly between individuals (Holomuzki et.

Detailed explanation-3: -Organisms from different species compete for resources as well, called interspecies competition. For example, sharks, dolphins, and seabirds often eat the same type of fish in ocean ecosystems. Competition can be direct or indirect.

Detailed explanation-4: -Intraspecific competition occurs between red and purple sea urchins when resources are limited, such as food and habitat space. Within sea urchin barrens, high densities of sea urchins with scarce food resources make conditions optimal for competition.
