What amount of carbon is fixed in the biosphere through photosynthesis

1.	What amount of carbon is fixed in the biosphere through photosynthesis annually?(a) 10^13 kg(b) 20 × 10^20 kg(c) 4 × 10^13 kg(d) 80 × 10^35 kgI had been asked this question by my college director while I was bunking the class.The origin of the question is Ecosystem in division Ecosystem of Biology – Class 12
Answer» Right choice is (c) 4 × 10^13 kg Explanation: Photosynthesis is a process in which producers (green plants) in the presence of CO2, WATER, sunlight, and chlorophyll yield energy and oxygen is released in the FORM of gas. The amount of carbon FIXED in the biosphere through photosynthesis annually is APPROXIMATELY 4 × 10^13 kg.
