Biotic and Abiotic Factors
• Biotic = living components of an ecosystem including anything that was once alive.
• Abiotic = non living components of an ecosystem. These were never alive.

Putting it all together What basic needs are met by an organisms
habitat? Food water shelter and other things it needs
to live.

Putting it all together Why do different organisms live in different
habitats? Because different organisms have different
needs for survival.

Putting it all together Using the word photosynthesis, explain
why water and sunlight are two abiotic factors that are important to all organisms

Species
A group of organisms that are physically similar and that can mate and produce fertile offspring.

PopulationAll the members of one species in a particular area.

CommunityAll the different populations that live together in an area.

EcosystemA community of organisms that live in an area along with their non living surroundings

Ecology
The study of how living things interact with each other and their environment.

Putting it all together Would all the
trees in a forest make up a population? Why or Why not?

Putting it all together What is the
difference between a community and an ecosystem?

Putting it all together Why do ecologists
study both the biotic and abiotic factors in an ecosystem?
