The correct answer is Egestion.Explanation:The egestion process involves the removal of undigested waste products and food from the organism's body.However, the excretion process in living beings involves the removal of wastes from the cells of organisms. Thus, egestion process cannot be considered as an essential characteristic of all living beings. Egestion is primarily happens through the anus or mouth. (Animals like jellyfish use their mouths to both eat and expel waste.)Only animals undergo esgestion. But excretion happens in both plants and animals.Additional InformationRespiration: Respiration is necessary for living organisms to survive. It releases energy from the food.The oxygen we inhale is used to breakdown glucose into carbon dioxide and water. During the process, energy is released.Reproduction:The biological process by which new individual organism "offspring" are produced from their "parent" or parents is referred to as reproduction. Each individual organism exists as a result of reproduction, which is a fundamental feature of all known life.Excretion: The process by which organisms expel metabolic waste products and other toxic substances from their bodies is referred to as excretion.
