Competition

200

This species interaction is between 2 species; one that hunts the other as food.

Predation

300

This species interaction is between 2 or more species that work for the benefit of all interacting species. (All sides benefit)

Mutualism

400

Species Interaction that has one species harming the other, but not killing it.

Parasitism

500

Any species interaction that is close and permanent between organisms of different species.

Symbiosis

Species Relationships

100

Community

200

Form of deception used by some prey as a means of defense against predators.

Mimicry

300

The number of different species found in the community.

Species Richness

400

Relationship between the number of species in the community AND the abundance of each species.

Species Diversity

500

A pattern that is seen where larger areas contain more species than smaller areas do.

Species-Area Effect

Levels of Organization

100

A group of similar organisms that can produce fertile offspring.

Species

200

Organisms that capture the sun's energy to use to make food.

Producers

300

Succession

400
