• D. chemical$\to$ heat

Answer 1

The correct option is B light $\to$ chemical

During photosynthesis light energy is converted into chemical energy. Light is absorbed in the form of photons by the green pigment chlorophyll and is converted into energy rich molecule ATP. $C{O}_2$ absorbed from the atmosphere and water absorbed from the soil in the presence of sunlight and chlorophyll is converted into glucose and oxygen.

$\text{Carbon dioxide}+\text{Water}\stackrel{\text{Sunlight}}{\to }\text{Glucose}+\text{Oxygen}$
