A

Organisms that can breed with one another and produce fertile offspring.

3
Q

Community

A

A community consists of all the organisms in all the interacting populations in a given area.

4
Q

Ecosystem

14
Q

Ecological Niche

A

The role an organism has on a community; including what it needs to survive and how it effects other organisms.

15
Q

Biodiversity

A

The variety of species in an area and there adaptivity to the environment.

16
Q

Limiting Factor

20
Q

Density

A

The number of individuals per unit. Can be measured by volume or area.
