How can patterns in the natural world be seen as evidence?

The selection of the option that states recognizing all living things need water and light highlights a fundamental pattern in the natural world that serves as evidence of the interdependence and common requirements of life. This observation demonstrates a basic biological principle applicable to nearly all organisms, reflecting how they are adapted to their environments.

The need for water is essential for biochemical processes, and light is crucial for photosynthesis in plants, illustrating fundamental ecological relationships. This understanding goes beyond mere observation; it indicates underlying biological and ecological principles that connect different life forms and ecosystems.

In contrast, while the other options provide interesting observations, they do not capture the same evidence of essential life processes. The idea that animals need food while plants do not does not provide a complete or accurate understanding of how life functions, as both groups have distinct needs crucial for their survival. Furthermore, identifying the uniqueness of each organism speaks to biodiversity but does not directly communicate the shared characteristics that unify all life forms. Therefore, option B best illustrates a clear and shared pattern that serves as powerful evidence of life's requirements.
