Adapt to their environments (evolve)

5. So what the heck is a species?
Species – an interbreeding population of organisms that can produce healthy, fertile offspring.

6. Levels of Organization: What makes up a species?

7. Levels of Interaction
Population – Group of organisms of the same species.
Community – populations of dif. Species interacting in the same area.
Ecosystem – a community of organisms interacting with the non-living factors in their environment.
Biosphere – The parts of the earth that sustain life. Land, water, and air. (all ecosystems)
