A group of organisms that can reproduce with one another.

A community of living (biotic) and non-living (abiotic) things and their interactions.

A group of individuals of the same species living in a specific area.

Species are not evenly spread; more diversity near the Equator.

System for classifying living organisms into five groups: Animalia, Plantae, Fungi, Protista, and Monera.

Inherited material that carries genetic information and variation.

Diversity of genes within a species or population.

The process by which the environment chooses which individuals survive and reproduce.

Changes in a species that enhance survival in a specific environment.

A group of finch species in the Galápagos that show variations suited to different food sources.

The relationships and exchanges that occur between communities and species in an ecosystem.

A kingdom that includes bacteria classified by physical structure.

An interaction between members of different species living together.

A type of symbiosis where one organism benefits and the other is unaffected.

A symbiotic relationship where both organisms benefit from the interaction.

A symbiotic relationship where one organism benefits at the expense of the other.

The role of an organism in its ecosystem, including where it lives and what it does.

Competition between different species for the same resources, neither benefiting.

Dividing resources among species to reduce competition through behavioral adaptations.
