Verified step by step guidance

Understand the levels of organization in the human body, which include: chemical, cellular, tissue, organ, organ system, and organismal levels.

Recognize that the organismal level is the highest level of organization, where all organ systems work together to maintain life and health.

Compare the given options: tissue level, organ level, cellular level, and organismal level.

Identify that the tissue level involves groups of similar cells performing a common function, the organ level involves structures composed of at least two tissue types, and the cellular level is the basic unit of life.

Conclude that the organismal level is the most encompassing level of organization, as it includes all other levels working together to form a complete living being.
