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>

The ATP and NADPH are used in the Calvin cycle to fix the atmospheric CO2 into glucose. The use of water as an electron donor releases oxygen gas as a by-product. This photosynthesis wherein the use of water as an electron donor releases oxygen gas as a by-product is also called oxygenic photosynthesis.

The mRNA that translates to form a enzymes is macromolecule because RNA is made of large units of nucleotides. Lipid that found in cell membrane are macromolecules because they are made of more than 1000 atoms. Protein that are involved in DNA replication are macromolecules as they have large units of amino acids.

Thus, all the given option are correct.
