Difference Between Population and Community in an Ecosystem

In ecology, "population" and "community" are terms used to describe different levels of biological organization within an ecosystem.
Population: Population refers to the number of organisms of the same species occupying a given habitat, for instance the population of elephants in a forest and the population of bacteria in a pond.
Community: A community is a broader term that encompasses all the populations of different species of plants and animals in a given area and are interacting with each other. Example: The populations of trees, birds, insects, mammals, fungi, and bacteria.
