Habitat An environment that provides the things an organism needs to live, grow and reproduce

The living parts of a habitat Biotic Factors The living parts of a habitat Panda Bamboo plants clown fish sea anemone

Abiotic Factors The non-living parts of a habitat Water Sunlight Oxygen Temperature Soil

Abiotic Factors The non-living parts of a habitat water temperature of water oxygen (dissolved in the water) oxygen (air) sunlight soil or dirt temperature

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.

Population All the members of one species in a particular area.

Community All the different populations that live together in an area.

Ecosystem A 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.

Ecological Organization Biome Larger Ecosystem Ecological Organization Community Population Smaller Single organism

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? Community Ecosystem

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