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.

Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the ...

The feeding sequence, showing the energy flow from producers to consumers, is called a food chain. Each step is called a trophic level: producers are on the first trophic level 1, primary ...
