Question

If $200J$ energy falls on the leaves of green plant. How much energy will be lost into the environment?

• A. $40J$
• B. $20J$
• C. $110J$
• D. $180J$

Answer 1

The correct option is D $180J$

$200\times \frac{10}{100}=20J$
$20J$ energy will be trapped by the plants to produce chemical or food energy.
SO, $200-20=180J$ will be lost into the environment.
