If $10,000 \;J$ of energy fall on piece of land, then what is energy available at $T_2$ level?
A
$1000\; J$
B
$10 \;J$
C
$100 \;J$
D
$1 \;J$
Solution
Since $10\;\%$ energy is received by next trophic level. Here $10,000\; J$ fall on earth its $1\;\%$ in producers $i.e.$, $100\; J$ so energy available at $T_2$ will be $10 \;J$ because further transfer is $10\;\%$.
