How To Describe The Levels Of Organization That Live In Your Biome

A biome is one of the six major types of biological communities that make up the biosphere: freshwater, marine, desert, forest, grassland and tundra. There are several levels of organizations within the biome; each layer is comprised of a larger group of living things than the layer before it.

Step 1

Pick out a single organism. The lowest level of organization in a biome is the individual organism. For example, a single fish in a marine biome is an example of an organism.

Step 2

Group organisms of the same type into a population. Thus, all fish in a specific marine biome would be a population.

Step 3

Add other organisms that are not of the same species, but that interact with the previously defined population. This is called a community, and for fish would include the micro-organisms that they eat, as well as any animals that prey on them.

Step 4

Add all other organisms (including those that have no relation to the community) and non-organic factors (like water, sunlight and soil) to get the final level of organization in the biome, namely the ecosystem.
