NEET Botany Energy Flow MCQ Question
If the incident solar radiation on a grassland ecosystem is 1000 J/m², and the percentage of photosynthetically active radiation (PAR) is 2-10%, what is the range of energy available as PAR?
20-100 J/m²
10-50 J/m²
50-200 J/m²
100-500 J/m²
Correct Answer
Detailed Explanation
Photosynthetically active radiation (PAR) is 2-10% of the incident solar radiation. Therefore, for 1000 J/m² incident, PAR is 20-100 J/m².
