Energy Flow

Let us study about Energy flow,
The branch of science which deals with the flow of energy into the ecosystem and its transformation into the living organisms is referred as a bio-energetics. The energy is essential for the existence of organisms. It helps to overcome entropy and to perform various life activities. The energy occurs in multiple forms and the one form of energy can be converted into the other form. Sun is the main source of energy.

There is a need of constant flow of energy from the sun to earth. The flow is unidirectional. It occurs from the sun to plants and from the plants to animals leading to the microbes with the dissipation of heat. The radiations from the sun can be short wave or long wave. The short wavelength radiations include the gamma rays, U.V rays and cosmic rays. The long wavelength radiations include the infrared waves. The very short wavelengths are very harmful to the organisms.

They cause the breakdown of inorganic components. The harmful radiations are filtered by the ionosphere and ozonosphere. The ionosphere is formed of the gamma rays, x rays and cosmic rays. The ozonosphere is formed by the U.V radiations.
I hope the above explanation was useful.
