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$(1kg)$
Justify the following statement in terms of ecosystem dynamics. “Nature tends to increase the gross primary productivity, while man tends to increase the net primary productivity”.
Assertion : A network of food chains existing together in an ecosystem is known as food web.
Reason : An animal like kite cannot be a part of a food web.
The second order consumer in a food chain is
