which of the following statements accurately describes how organisms are organized into smaller units?
○ organisms are made up of cells to atoms to tissues to organs to organ systems.
○ organisms are made up of tissues to cells to atoms to organs to organ systems.
○ organisms are made up of atoms to cells to tissues to organs to organ systems.
○ organisms are made up of organs to organ systems to cells to atoms.

Explanation:

The hierarchical organization of biological organisms from largest to smallest units starts with organ systems, which are composed of organs. Organs are made of tissues, tissues are made of cells, and cells are ultimately composed of atoms. This means breaking down an organism into smaller units follows the order: organ systems → organs → tissues → cells → atoms.

Answer:

Organisms are made up of organs to organ systems to cells to tissues to atoms.
