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.

The way energy passes through an ecosystem is described as energy flow. Herbivores (plant eating animals) are primary consumers. Carnivores (animals who eat other animals) are secondary consumers ...

Each food chain is a descriptive diagram including a series of ... of energy transfer in terrestrial and aquatic ecosystems. Patterns of energy flow through different ecosystems may differ ...
