Detailed explanation-1: -Territoriality is a type of intraspecific or interspecific competition that results from the behavioral exclusion of others from a specific space that is defended as territory. This well-defined behavior is exhibited through songs and calls, intimidation behavior, attack and chase, and marking with scents.

Detailed explanation-2: -Territoriality is the behavior by which an animal lays claim to and defends an area against others of its species, and occasionally members of other species as well. The territory defended could be hundreds of square miles in size, or only slightly larger than the animal itself.

Detailed explanation-3: -Many animals are territorial as adults. This strategy often makes evolutionary sense since animals can defend clumped resources more efficiently if they stake out a space of their own.

Detailed explanation-4: -Because animals need a place to live and access to resources, they also fight over territory. Some are more territorial than others, but all must stake their claim somehow.
