In the following food chain, $$\begin{aligned}& 5 \\ & \text{J}\end{aligned}$$ of energy is available to man. Calculate, how much energy was available at the producer level. Why ?
Plant $\longrightarrow$ Goat $\longrightarrow$ Man
Plant $\longrightarrow$ Goat $\longrightarrow$ Man

Plant $\rightarrow$ Goat $\rightarrow$ Man
According to 10 % Law, only 10% of energy from a trophic level is transferred to the next trophic level.
So, if Man has 5 J energy
then Goat has $5 \times 10 = 50$ J
And plants (producers) have $50 \times 10 = 500$ Joule
