Energy transfer from one trophic level to another in a food chain is: (in $\%$)

If the biomass of a lion in a food chain is $10 \ kg$,then the biomass of the producers is approximately ...... $kg$.

Flow of energy through various trophic levels in an ecosystem is unidirectional and non-cyclic. Explain.

Food and energy relationships among living components of an ecosystem are generally referred to as:

$10 \%$ law of energy transfer was given by

$A$ plant receives $10000 \ J$ of energy from the sun. The amount of energy that will be present at the third trophic level is $:-$ (in $J$)
