• diversity

An ecosystem is made of both biotic and the abiotic things. Which describe the biotic part of the ecosystem?

• plants that grow in soil
• the animals that breathe oxygen
• all living things in an environment
• plants and animals that live in water

This is the type of factor that determines the size and type of population in the ecosystem.  An example of this would be the availability of food, water and shelter.
