Why the sun is the ultimate source of an opossum's energy?

The sun is the ultimate source of an opossum's energy because it drives the process of photosynthesis in plants, which form the base of the food chain. Opossums primarily feed on fruits, insects, and small animals that rely on plants for energy. Through this food web, the solar energy captured by plants is transferred to opossums, allowing them to obtain the nutrients and energy needed for survival. Thus, the sun indirectly powers their biological functions and daily activities.
