Detailed explanation-1: -Mates. Animals within a species also compete for mates. This is essential so they can pass on their genes to their offspring. Animals have evolved to have an innate or natural drive to reproduce, and this competition often results in fights.

Detailed explanation-2: -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-3: -Many mammals have similar breeding behavior to this-lions, gorillas, and kangaroos all fight over who gets to mate with nearby females. This fighting is a form of agonistic behavior, which is a behavior associated with conflict over access to a resource (including mates).

Detailed explanation-4: -Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.

Detailed explanation-5: -Animals compete for air, food, shelter, water, and space. Plants also compete with each other for the resources they need, including air, water, sunlight, and space. These interactions within an ecosystem help keep the populations of various organisms in balance and are necessary to keep an ecosystem healthy.
