Naddika [18.5K]

Answer:

population - community - ecosystem - biosphere

Explanation:

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.

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.

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

Its main functions are secretion and absorption. It has an abundance of organelles to facilitate active transport frequently found in glands, such as salivary glands, the thyroid gland, and the pancreas, where its function is secretion.

The epithelial cells tend to be cubical in form after they are inactive, however additional columnar after they are actively secreting hormones.
The epithelial cells accumulate iodine from the blood and use this component within the synthesis of thyroglobulin, an oversized compound protein that forms the mixture.
