Which of the following correctly sorts the organizational levels of a ecosystem form least inclusive to most inclusive
Naddika [18.5K]

Answer:

population - community - ecosystem - biosphere

Explanation:

<em>The correctly sorted level of organization of an ecosystem from the least inclusive to the most inclusive would be from population to community to ecosystem and finally to biosphere.</em>

A population consists of a group of organism of the same species living in a particular area at a particular time and capable of interbreeding to produce fertile progeny.

A community represents different population of organisms that are interacting with one another. Several populations make up a community.

An ecosystem consists of different communities of organisms that are interacting with themselves and the non living component of the environment.

A biosphere consists of all regions of the earth where living organisms can be found. It consists of different ecosystems that make up the earth.

<u>Hence, the population is least inclusive, followed by the community, then the ecosystem and finally the biosphere.</u>
