This is one of the biogeochemical cycles; it has both a sedimentary and gaseous phase, enters biological cycles through photosynthesis, and is the largest contributor to acid rain and smog.

The answer is; Carbon Cycle

Carbon exists in the atmosphere as carbon dioxide. It is incorporated into the biosphere through photosynthesis where it is converted to carbohydrates. When carbon-based compounds are burned in air, carbon dioxide is produced and when it moves with precipitation, it causes acid rain (carbonic acid).

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
