Which behavior is characterized by an animal defending its territory?

Territoriality is defined as a behavior in which an animal defends a specific area against others of its species, ensuring access to resources such as food, mates, and nesting sites. This behavior is crucial for the survival and reproductive success of individuals, as it helps reduce competition for limited resources and can provide an advantage in breeding.

In this context, while foraging pertains to the behavior of searching for and gathering food, migratory behavior refers to the seasonal movement of animals from one habitat to another, and parental investment relates to the care and raising of offspring, none of these involve the active defense of a specific territory. Territoriality represents a distinct behavioral strategy focused on the protection and maintenance of an area that is vital for an animal's survival and reproductive success.
