Species
A group of living organisms that are similar to each other and can interbreed.

Community
Groups of different organisms interacting in a common location.
Habitat

Natural Selection
A process in which the most fit or best adapted survive to pass down their genes.
Evolution
The change in a species over grand amounts of time.
Producers/Autotrophs
Organisms that produce their own food, and are food for other organisms.
Consumers/Heterotrophs
Consumers consume producers. They cannot make their own food, so they have to consume producers.
Primary Consumer
A consumer in an energy pyramid, that consumes the producer. It is one step above the producer.
Secondary Consumer
It is the step above the primary consumer. The secondary consumer usually consumes the primary consumer. There are fewer secondary consumers than primary consumers.
Tertiary Consumer
This is the highest step in the energy pyramid and is above the secondary consumer. These consumers eat the secondary consumer, and are often at the peak of the food chain. These consumers are the fewest in number and require the most energy.
