Answer:
Lipids:
Lipids may be defined as the class of organic compounds that are either fatty acids or their derivatives. Lipids mainly composed of a glycerol molecule, long hydrocarbon chains and a phosphate or other chemical group. The main function of lipids are: They acts as energy fuel and acts as a main constituent of plasma membrane.
Starches
Starch may be defined as a type of carbohydrate and present in plants as well as animal. Starch mainly composed of large glucose units linked through the glycosidic bonds. The main function of starch is to provide energy to an organism.

Answer:
Phenotypic variation is the variation which appears in the phenotype or morphology of the organism. Natural selection is the mechanism of evolution in which the adapated organism to the environment is selected or highly favoured during the course of evolution.
A phenotype is the results of the genetic change which to be established in a population has to be passed on to the generation.
Since variation in phenotypic traits allows the organism to leave indifferent circumstances therefore phenotypic variation proves essential condition to natural selection.
