 A group of individuals that breed with one another and belong to the same species make up a population.

• A population is defined as a group of organisms of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are influenced by similar environmental factors, and are likely to interact and breed with each other. Populations are studied on various levels such as size, structure, and distribution.
• The size of a population is determined by the number of individuals it contains. Population structure pertains to the age distribution and sex ratio within the group, and population distribution refers to how those individuals are spread out over the area they occupy. Understanding population dynamics is important for conservation biology, ecology, and wildlife management, as it pertains to the health and sustained existence of species.
