Energy in an ecosystem
The vast majority of energy in food webs originates from the sun. Energy is not recycled in ecosystems and each ecosystem requires a continuous input of energy to sustain it. There is some energy transformed at each level of the food chain or food web in an ecosystem. In an ecosystem, energy is frequently transformed from one form to another.

A small stream running through a wooded catchment derives most of its energy input from litter shed by surrounding vegetation (Figure 17.4). Shading from the trees prevents any significant growth of planktonic or attached algae or aquatic higher plants. As the stream widens further downstream, shading by trees is restricted to the margins and ...

Ecology/Energy in ecosystems
Energy flow is the amount of energy that moves through a food chain. The energy input, or energy that enters the ecosystem, is measured in Joules or calories. Accordingly, the energy flow is also called calorific flow. In the study of energy flow, ecologists try to quantify the importance of different species and feeding relationships.

Energy Transfer in Ecosystems
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next. The easiest way to demonstrate this energy flow is with a food chain.
Energy Balance of Ecosystems
There are three balances that should be considered together if anyone would like to characterize the energy balance in the ecosystem fully. They are radiation balance, heat balance, and water balance (Figure 1).Radiation balance determines the energy (leaving out nuclear and geothermal energy) being the moving force of all processes and support of life, as …
