    An organism’s environment is all the living and nonliving things that surround and influence the organism(生物体). You are living with many things that make your environment suitable for you to live in. Would that be true if you lived in a swamp(沼泽)?

Environments include biotic parts and abiotic parts. Biotic parts are the living things in an environment: plants, animal, and other organisms. Abiotic parts are the nonliving things. Abiotic parts of an environment include climate, water, earth, light, air and nutrients. The abiotic parts of an environment have an important role. Temperature and amount of water influence which plants and animals can live in a place. An ibis(朱鹮) gets used to living in a warm, wet swamp and cannot live in a hot, dry desert.

An ecosystem is all the organisms living in a place together with their environment. An ecosystem can be huge, such as a large forest or desert. Or it can be small, such as a small pool or a single bush. Each ecosystem has its own collection of living and nonliving things.

A swamp ecosystem is made up of both living and nonliving things. The climate, plenty of water, air, muddy soils are all abiotic parts that make swamps different from other environments. Birds, black bears, trees, bushes, and mosquitoes are all biotic parts of a swamp environment.
