The primary source of energy for most ecosystems is sunlight, which is harnessed by plants through the process of photosynthesis. These producers convert solar energy into chemical energy, forming the base of the food chain. Herbivores then consume the plants, transferring energy to higher trophic levels, including carnivores. In some ecosystems, such as deep-sea hydrothermal vents, chemosynthesis serves as an alternative energy source, relying on chemical reactions rather than sunlight.
