The terms population and community are sometimes used interchangeably, but they have distinct meanings. A population is a group of individuals of the same species in the same area. A community, on the other hand, is a more complex structure that includes the population as well as the physical and chemical environment in which the population lives.
A population is typically focused on the individuals, such as the number of individuals, their sex, age, size, etc. A community also considers the interactions between the population and the environment, such as the availability of food, water, and shelter. A community is a more holistic view of an area, while a population focuses on the individuals within it.
