Explanation:
Detailed explanation-1: -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: -Triglycerides are the primary form of long-term energy storage in plants and animals.
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.
