Question

The primary source of energy in most ecosystems is/are

Answer 1

The primary source of energy in most ecosystems is sunlight. Through the process of photosynthesis, plants and some microorganisms convert solar energy into chemical energy in the form of glucose, which serves as the foundation for energy flow in food chains and ecosystems. These photosynthetic organisms, or producers, are essential for supplying energy to herbivores (primary consumers) and, subsequently, to carnivores (secondary and tertiary consumers) in the ecosystem.
