Multiple choice

The plants convert light into chemical energy with a photosynthetic efficiency of:

  1. 3 - 6%

  2. 6 - 20%

  3. 20 - 35%

  4. 35 - 41%

A Correct answer
Explanation

Plants typically convert only 3-6% of absorbed light energy into chemical energy (biomass) due to reflection, photochemical inefficiencies, and metabolic losses. Higher values like 35-41% are physically impossible under natural conditions.
