Answer: False

Explanation:

Protozoans are not the organism that fix nitrogen for the plants. The organism that fix nitrogen to convert it into a form which can be used by plants are known as diazotrophs.

These are bacteria and archae that fix nitrogen gas found in the atmosphere into more usable form such as ammonia.

These organism can grow without any external source of fixed nitrogen. Example: Rhizobia and azospirillium.

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>
