<span>Carbohydrates
are composed of single sugar units that make u starches which offer a ready
source of your cell’s fuel. These units constitute monosaccharide,
double-monosaccharide units called disaccharides and multiple-monosaccharide
molecules while lipids are molecules that constitute hydrocarbons and make up
the building blocks of the structure of living cells which stores energy in fat
tissues for future uses. Both lipids and carbohydrates offer essential
nutrients to diet. Both of them play an
important role in absorption and digestion but have their own mechanic ways.</span>

But the global temperature is rising due to lost of carbon dioxide present in the environment as the burning of fossil fuels is increasing day by day.
