What is the transfer of energy law in the grazing food chain?
Options
- A50 per cent law
- B20 per cent law
- C10 per cent law
- D5 per cent law
Correct answer
C. 10 per cent law
Step-by-step solution
Each trophic level has a certain mass of living material at a particular time called as the standing crop. The standing crop is measured as the mass of living organisms (biomass) or the number in a unit area. The biomass of a species is expressed in terms of fresh or dry weight. Measurement of biomass in terms of dry weight is more accurate. Why?The number of trophic levels in the grazing food chain is restricted as the transfer of energy follows 10 per cent law – only 10 per cent of the energy is transferred to ea
