Energy Flow Through The Ecosystem

In an ecosystem, organism are linked together in energy and nutrient relationship. The energy can be defined as the capacity so do work. The term work can be used to any energy consuming process such as living cells maintain electrical gradient across membrane and the active transport process which requires expenditure of energy. However, the ecological studies relating food requirement and energy relationship among living components of an ecosystem are referred as bio-energetics. Energy is found in four main forms i.e , radiant energy, heat energy, chemical energy and mechanical energy. Only a small part of solar energy is visible spectrum.
