Community: All of the populations of species in an ecosystem or habitat

4. Biotic Factors: The living part of the environment
Decomposers, animals, plants
Abiotic Factors: The non-living part of the environment
Space, temperature, oxygen, light, water

5. How do biotic and abiotic factors affect ecological interactions?
They both contribute to the characteristics of an ecosystem
Abiotic factors influence the distribution of organisms in an area
Biotic factors depend on the presence of other living things
Predator/prey relationships can’t exist if there is no predator
