NEET Botany Food Chains & Webs MCQ Question
If a grassland ecosystem receives 1000 units of solar energy, and plants capture 5% of the photosynthetically active radiation (PAR), how much energy is available to the primary consumers?
5 units
25 units
50 units
10 units
Correct Answer
Detailed Explanation
Plants capture 2-10% of PAR. If they capture 5% and PAR is 50% of incident solar energy, then 1000 * 0.5 * 0.05 = 25 units are available to primary consumers.
