Detailed explanation-1: -For example, animals may compete for territory, water, food, or mates. Competition often occurs between members of the same species. This is called intraspecific competition. This is the type of competition that is the driving force behind natural selection within a species.

Detailed explanation-2: -Intraspecific competition is an interaction in population ecology, whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce.

Detailed explanation-3: -Two main forms of sexual selection occur: intrasexual selection and epigamic selection. In intrasexual selection males (or more rarely females) compete through display or physical contest for mates. In epigamic selection females accept males (or occasionally the reverse) with certain traits.

Detailed explanation-4: -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.
