Question

In the food chain-
$Grass\to deer\to lion,$
operating in a forest, what will happen If 100J of energy is available to the producers in this ecosystem, how much energy will be available to the Deer?

Answer 1

According to lindemann $10\%$ law, during the transfer of energy from organic food from

one trophic level to the next, only $10\%$ energy is stored as flesh.

According to question $100J$ energy is available to producer

So, $Grass\to deer\to lion$

(Producers)

$100J\to 10J$

So, $10\%$ of $100J$ is $10J$ will be available to Deer in this ecosystem.
