Final answer:
The correct representation of the levels of organization in living systems is Cells - Tissues - Organs - Organ Systems - Organisms - Ecosystems.
Step-by-step explanation:
The correct representation of the levels of organization in living systems is D) Cells - Tissues - Organs - Organ Systems - Organisms - Ecosystems.
In this hierarchy, cells are the basic unit of life and are organized into tissues. Tissues then form organs, which work together to form organ systems within an organism. Multiple organisms interacting with each other and their nonliving environment make up an ecosystem.
For example, in the human body, cells combine to form tissues, such as muscle tissue. Different tissues then form organs, like the heart. Multiple organs working together make up organ systems, such as the circulatory system. An organism is a complete living being, like a human, and ecosystems include all the living organisms and their environment in a specific area, like a forest.
