Photosynthesis is the dominant source of energy in most ecosystems through conversion of light to C-H bonds in organic material, and so the flow and fate or carbon is tightly linked to energy flow.

Pyramids of energy show that the producers store the highest quantity of energy and the energy stored then decreases at each level in the food chain of the ecosystem.

All organisms in an ecosystem depend on each other. Food chains show the flow of energy from one organism to another. Food chains show the feeding relationships between organisms. Food webs show ...
