The flow of energy between various or many components of the environment has been extensively studied. List four findings.

The flow of energy between various or many components of the environment are:
• Flow of energy is unidirectional.
• about 1% of the Sun’s energy take Terrestrial plants and changes it to chemical energy.
• A great energy is – lost as heat/ used for digestion/doing work/growth and reproduction.
• About 10% of organic matter present at each trophic level (and available for next level of trophic).
• Food chains are mainly of 3 to 4 trophic levels (as because of 10% law) .
• The number of producers are maximum (the number reduces in subsequent trophic levels).
• Food webs are more common (as compared to isolated food chains).
• Biological magnification can be observed.
