Population
Definition:
• Population is the total number of individuals of the same species living in a specific area at a particular time.
Why is population important?
Population is important because it determines how living organisms survive, interact, and use resources in an area.
• Population size helps us understand how many individuals of a species are living in a place and whether their numbers are increasing or decreasing.
• It affects the availability of food, water, space, and shelter, since resources are limited.
• Population studies help explain competition, predator–prey relationships, and balance in ecosystems.
• Knowing population trends helps in conservation, so endangered species can be protected and overpopulation can be controlled.
• For humans, population data helps in planning for schools, hospitals, jobs, housing, and transport.
In short, population is important because it helps maintain ecological balance and supports proper planning and survival.
