The percentage of sunlight energy absorbed by the green plants in a terrestrial ecosystem is about _______.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1%.
In a terrestrial ecosystem, only about 1% of the sunlight energy that reaches the Earth's surface is absorbed by green plants for photosynthesis. Although sunlight is abundant, plants convert just a small fraction of this energy into chemical energy to produce food. This limited efficiency is due to factors like reflection, transmission, and the plants’ biochemical limitations. The absorbed energy supports plant growth and forms the base of the food chain, sustaining herbivores and higher trophic levels. Despite being a small percentage, this energy capture is crucial for life on Earth, driving ecological processes and maintaining ecosystem balance.
