Solution

The correct option is C $C O_{2}$ is converted in photosynthesis to carbohydrates
Respiration is the process wherein living organisms take in atmospheric oxygen and release $C O_{2}$ in the atmosphere. Photosynthesis is the process wherein green plants fix atmospheric carbondioxide in presence of sunlight into carbohydrates. So, carbondioxide released into the atmosphere by respiration is counterbalanced by its photosynthetic fixation.

?

Q. Assertion :The atmospheric concentration of

C O_{2}

at which photosynthesis just compensates for respiration is referred to as

C O_{2}

compensation point. Reason: The

C O_{2}

compensation point is reached when the amount of

C O_{2}

uptake is less than that generated through respiration, because the level of

C O_{2}

in the atmosphere is more than that required for achieving

C O_{2}

compensation point.

In air , all the consisting gases remain uniformly mixed. Co2 which is lower than both N2 and O2 does not form the lower layer in the atmosphere. Why?
