Detailed explanation-1: -Fats (lipids) Fats are the primary long-term energy storage molecules of the body. Fats are very compact and light weight, so they are an efficient way to store excess energy. A fat is made up of a glycerol, which is attached to 1 to 3 fatty acid chains.
Detailed explanation-2: -Animals store energy in the form of lipids rather than in the form of carbohydrates because lipids have a higher energy content. This is because lipids have a higher ratio of hydrogen atoms to carbon atoms than carbohydrates and the energy content of organic molecules is in the carbon-hydrogen covalent bonds.
Detailed explanation-3: -Organisms use lipids to store energy. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids. Animals use saturated fatty acids to store energy. Plants use unsaturated fatty acids to store energy.
Detailed explanation-4: -triglycerides: the main form of stored energy in animals.
