What would happen if photosynthesis stopped happening on earth?
a; there would be more oxygen in the air
b ; sun would produce less energy
c ; carbon dioxide levels would increase
d; biodiversity would increase in rain forest

The correct answer is option C

Photosynthesis is the process by which green plants make their own food by the help of carbon dioxide, sunlight and chlorophyll. The green plants produce oxygen in the air and utilize the carbon dioxide present there. If there will be no photosynthesis on the earth then there will be increased amount of carbon dioxide on earth.
