How does population ecology differ from community ecology?

Population ecology is the study of populations; specifically, how populations change over time and what environmental factors contribute to that change. Community ecology is the study of communities; specifically, the organization, function, and interactions between species or populations within a community.

What are the differences between population community and ecosystem?

An organism is a single living thing, a population is all of the organisms of the same species in the same place at the same time, a community is all populations in the same place at the same time (all living things), and an ecosystem is the reactions between living and nonliving components in a given area.

What is the difference between community and ecology?

If we put populations of different species together, that’s called a community. So, a community needs groups of different species to exist. When we add in the abiotic factors, or non-living things in an environment, we get an ecosystem.
