Answer :
Explanation :
In the process of photosynthesis, plants need the sun's energy, water to make food for themselves in the form of ATP ( adenosine triphosphate ) , which is packages of energy. Carbon : coming into the plants ( or algae ) along with water make those ATP into a bigger molecule, which is know as glucose. Formula: 6 CO2 + 6 H2O + Suns Energy -> glucose + oxygen Photosynthesis has an affect on the carbon cycle because it reduces the amount of CO2 in the air and redirects it into sugars which feeds animals as well as humans. Hence, Photosynthesis removes CO2 from the atmosphere and replaces it with O2.

Answer : 2. "1/6"
Explanation :
Answer: B) 1/6 Explanation: Total work is given by L.C.M of 72, 48, 36 Total work = 144 units Efficieny of A = 144/72 = 2 units/day Efficieny of B = 144/48 = 3 units/day Efficieny of C = 144/36 = 4 units/day According to the given data, 2 x p/2 + 3 x p/2 + 2 x (p+6)/3 + 3 x (p+6)/3 + 4 x (p+6)/3 = 144 x (100 - 125/3) x 1/100 3p + 4.5p + 2p + 3p + 4p = 84 x 3 - 54 p = 198/16.5 p = 12 days. Now, efficency of D = (144 x 125/3 x 1/100)/10 = 6 unit/day (C+D) in p days = (4 + 6) x 12 = 120 unit Remained part of work = (144-120)/144 = 1/6.
