In relation to energy transfer in ecosystem, explain the statement "$10$ $kg$ of deer's meat is equivalent to $1$ $kg$ of lion's flesh".
The flow of energy in ecosystem is unidirectional. From the energy obtained in first trophic level transferred $10 \%$ energy to second trophic level.
deer($10 \;kg$ biomass)$\underset{energy \;lost\; in \;respiration\; and \;other\; processes\; 90 \% (means 9 \mathrm{~kg} )}{\rightarrow}$ lion$(1kg)$
