A close interaction between two different organisms, with at least one benefits.

Any living organism that is not native to an ecosystem and causes harm.

A community of living organisms (plants, animals and microbes) in a particular area

The variety of all living things and their interactions.

A diagram that shows the amount of energy that moves through food chain.

Maximum population size of a biological species that can be sustained by that specific environment.

One organism benefits and the other is unaffected.

A symbiotic relationship in which both organisms benefit.

One organism benefits while the other is harmed.

Nonliving things in an ecosystem.

All of the living (or once living) things in an ecosystem.

A biome is a different form of an ecosystem in which a large land area with a distinct climate and plants and animal species exist.

Living or growing naturally in a particular place or region
