What is the percentage of energy that is transferred from the lower trophic level of a food chain to its higher trophic level?
Correct Answer : c ) 10%Explanation :
The energy transfer in an ecosystem follows ten percent law. As per this law, only 10 % of total energy available at any trophic level passes to higher trophic level. Rest of energy is lost to environment in the form of heat. Some amount of energy is consumed by organisms at lower trophic level for their own growth and development.
Hence, option (c) is correct.
Questions related to Environment and Ecology are asked in various government exams like State PCS, SSC CGL, UPSC CDS, SSC CHSL, etc.
