2%
B.
4%
C.
6%
D.
10%
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
The percentage of solar energy/radiation used in photosynthesis is 10%.Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Plants absorb sunlight, light energy from the sun is used to split water molecules (photolysis). The sunlight hits chloroplasts in the plant to produce food. This causes an enzyme to split the water. Water, when split, gives oxygen, hydrogen and electrons.
