Yes it is.
Carbon dioxide goes through plants, which they turn into oxygen. Humans and animals take in the oxygen and breathe out carbon dioxide. Then it repeats.
The topsoil is the upper and outermost layer of soil, usually the top 2 inches to 8 inches. It contains the highest concentration of organic matter and microorganisms. Topsoil is used as the medium for all plant growth, whether it is a lawn, garden or prairie.
Polysaccharide formation allows organism to store energy efficiently. The storage form of food in animals is glycogen and in plants it is starch. Both glycogen and starch are polysaccharides of glucose. Many glucose units are linked together by condensation reaction to form polysaccharide. Compared to having several molecules of glucose in a bulk it is better to store it in the form of condensed bulk i.e polysaccharide. Thus polysaccharides which are formed by condensation reaction i.e by the loss of water molecules are easy to store.
Polysacchrides are: a) stored in the form of condensed bulk
b) they are chemically non-reactive
c) they are osmolytically inactive
