The six levels of ecological organization are species, population, community, ecosystem, biome, and biosphere.
Work Step by Step
A species is a group of organisms that breed with one another, producing offspring that are fertile. Organisms of the same species residing in the same area form a population. A community is a group of different populations living in a specific region. An ecosystem consists of all organisms living together and their environment. Several ecosystems that share similar characteristics such as climate and having the same types of organisms living in them make up a biome. The biosphere is made up of the whole planet with its organisms and the environment.
