What Are the Levels of Ecological Organization?

The levels of ecological organization are the biosphere, biome, ecosystem, community, population and individual. Ecological organization helps people understand the structure and function of entire groups of microbes, plants and animals individually and as a whole.

The Earth is a biosphere. It includes all living organisms, both plants and animals, as well as every biome on Earth. Biomes are specific regions that share like ecosystems. There are desert, forest, tundra, grassland and aquatic biomes on Earth. Each of these major biomes is divided into distinct types. For instance, the forest biome is divided into temperate, tropical and boreal forests.

An ecosystem includes a specific community of living organisms, but also includes other abiotic factors, such as rocks, water, air and temperature. A community consists of all organisms in an area at a given time. Communities are normally biologically diverse.

A population is a given species in an area at a given time. Populations include different genetic makeup of the same species. For instance, the human population includes various ethnicities. Lastly, individual can be defined as any living species or organism. Individuals do not breed with individuals from other groups. Animals are very definite concerning cross-breeding, while some plants do cross-breed with other plants.
