If the ecosystem is balanced, which populations should be the largest? the smallest?

The correct answer is - Largest: producer, smallest: tertiary consumer or predators.

Explanation:

An ecosystem is a community of different populations in a particular region and interacts and works together. In a balanced ecosystem, the condition is the same but there is no effect of the factors exist in the ecosystem.

The largest population will be producers due to their ability to create storage energy from light energy and all ecosystem depend on them where the smallest population will be top-level trophic it can be a secondary or tertiary consumer as there is less energy than other trophic levels.

Thus, the correct answer is - Largest: producer, smallest: tertiary consumer or predators.

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
