Verified step by step guidance

Begin by understanding the levels of biological organization, which range from the smallest, such as atoms and molecules, to the largest, such as the biosphere.

Recognize that the organ system level is a higher level of organization that involves multiple organs working together to perform complex functions necessary for life.

Identify examples of organ systems, such as the digestive system, which includes organs like the stomach, intestines, liver, and pancreas working together to process food and absorb nutrients.

Differentiate between other levels of organization: amino acids are at the molecular level, mitochondria are at the cellular level, and epithelial tissue is at the tissue level.

Conclude that the digestive system is the correct example of the organ system level of biological organization, as it involves multiple organs functioning together.
