Verified step by step guidance
1
Begin by understanding the hierarchy of biological organization, which typically follows this order: cell, tissue, organ, organ system, and organism.
Recognize that each level of organization is composed of the previous level. For example, tissues are made up of cells, organs are made up of tissues, and organ systems are made up of organs.
Consider the definition of an organism: it is a complete living entity capable of independent existence, which includes all the organ systems working together.
Identify that the organism level is the most inclusive because it encompasses all other levels, including cells, tissues, organs, and organ systems.
Conclude that the organism level is the correct answer as it is the highest level of organization and includes all other levels within it.
