Final answer:
The correct graphical representation of organizational levels in a biological system is a Hierarchical tree, which highlights the progression from less complex to more complex forms, such as from molecules to the biosphere.
Step-by-step explanation:
The correct graphical representation of the organizational levels of a biological system is the Hierarchical tree. Biological systems are organized in a hierarchical structure, which starts from the smallest unit (atoms, molecules) and builds up through various levels of complexity, including cells, tissues, organs, organisms, populations, communities, ecosystems, and ultimately the biosphere. This structure can best be represented as a tree, where each branch leads to more specialized and less complex forms, resembling a family tree that branches out progressively.
Example of Organizational Levels in Biology:
- Hierarchical tree
- Ecological pyramid
- Ecosystem dynamics
