Which is correct for a food chain?
A
90% loss of energy or food at each successive trophic level
B
Transfer of food from one trophic level to next higher one as per Lindeman's ten per cent law
C
Transfer of energy from one trophical level to next higher one as per ten per cent law
Correct option is C. Transfer of energy from one trophical level to next higher one as per ten per cent law
A. Only 10% of energy is passed from one trophic level to next and rest 90% of the energy is lost in the form of heat or in respiration.
B. The organisms of higher trophic levels feed on the organisms of lower trophic level and in this way food is transferred from one trophic level to the next higher trophic level. Through this transfer, energy is transferred to subsequent higher trophic levels as per Lindeman's 10 per cent law.
C. Transfer of energy from one trophic level to next higher trophic one follows 10 per cent law or Lindeman's law of trophic efficiency which states that only 10% of the energy is passed from one trophic level to next and rest is lost in the form of heat or in respiration.
Hence, all statements given in the question are correct.
So, the correct answer is options 'A, B and C'.
