Select the ultimate source of energy for nearly every organism on this planet.

Question

Quizplus · Accepted Answer

The sun is the ultimate source of energy for nearly every organism on this planet, as it provides the energy for photosynthesis in plants and algae, which then becomes the base of the food chain for other organisms. Even organisms that don't directly rely on photosynthesis still ultimately get their energy from the sun through the consumption of other organisms that do. Heat, sugars, and plants are all important sources of energy for different organisms, but they all trace back to the sun as the original source.
