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.
