How is an ecosystem different from a community?

• They are the same

• An ecosystem includes the interaction between a community of organisms (biotic factors) interacting with their environment  (abiotic factors) 

• An ecosystem has only abiotic factors

• An ecosystem is more specific

All the nonliving parts of an ecosystem are referred to as:

• the community

• biomes

• biotic factors  

• abiotic factors
