Final answer:
Biological properties define life and living organisms are part of a structured hierarchy from organelles to the biosphere. Biological system models help visualize and study the complex interactions between these levels of organization.
Step-by-step explanation:
Living organisms are characterized by certain properties that define life, such as the ability to grow, reproduce, and maintain a stable internal environment known as homeostasis. When examining living organisms, we can look at various levels of organization, from the smallest units like organelles within a cell to the largest scale like the biosphere, which encompasses all ecosystems.
Systems thinking is particularly useful in biology for understanding complex interactions and processes. Biological system models can be simple diagrams or complex simulations, and they help in visualizing and predicting behaviors within these systems. For instance, models can depict how nicotine affects cells in the nervous system.
The biological levels of organization in living organisms are highly structured, ranging from organelles to cells, tissues, organs, organisms, ecosystems, and ultimately the biosphere. This hierarchical arrangement demonstrates how living things are interconnected and how biological systems can be used to study the complexity of life.
