Question

A student makes a model to represent the levels of biological organization, as shown. If the top of the pyramid represents the basic unit of life, how should each section be labeled?

1) Cells, Tissues, Organs, Organ Systems
2) Atoms, Molecules, Cells, Tissues
3) Organs, Organ Systems, Cells, Tissues
4) Tissues, Organs, Cells, Organ Systems

Answer 1

The correct order of the levels of biological organization in ascending order of complexity is 1. Cells, Tissues, Organs, Organ Systems.

Step-by-step explanation:

The question pertains to the categorization of the different levels of biological organization that make up living things. Given that the pyramid's top should represent the basic unit of life, the correct order starting from the top should depict this basic unit followed by the subsequent hierarchical levels that it makes up. The levels of organization should be labeled in ascending order of complexity as follows: Cells, Tissues, Organs, Organ Systems. This is because cells are the basic unit of life; tissues are groups of similar cells that perform a shared function; organs are collections of tissues that function together in a specific biological activity, and organ systems are groups of functionally related organs.

The correct order to label each section is 4) Tissues, Organs, Cells, Organ Systems. This represents the correct hierarchy of living organisms, starting with cells as the basic unit of life, followed by tissues, organs, and organ systems.
