normal
Energy transfer from one trophic level to other, in a food chain is
A
$1\%$
B
$2\%$
C
$10\%$
D
$20\%$
(AIPMT-1999)
Solution
(c)As per $10$ percent law, only $10\%$ of the energy fixed at one trophic level is passed to next trophic level. For example, when plants are eaten by animals only $10\%$ of energy of the food is fixed into animal flesh; rest is lost through respiration.
