Ecological Organization

Population

A group of organisms all the same species that live within a geographic area. (Biotic)

Species

A group of organisms so closely related they can interbreed and produce offspring that can interbreed.

Organism

A single member of a population. (Biotic)

Ecosystem

All of the living (community) and non-living materials within a geographic area. (Biotic and Abiotic)

Community

All of the populations that live within a geographic area. The organisms that make up the food web. (Biotic)

Biosphere

Global sum of all life on earth. (Biotic)

Biome

Large region on earth where the community of plants and animals have similar adaptations to help them survive in their environment. Determined by the latitude as well as land features, although some are aquatic. Land examples include: tundra, taiga, temperate deciduous forest, grasslands, desert, and tropical rainforest. Water examples include: marine, freshwater. (Biotic and Abiotic)
