The advantage of extracellular digestion

Introduction:

Animals share many of the same nutritional requirements, but their mode of obtaining and processing the nutrients differ in various ways. Several factors determine how and when an animal obtains food, including its energetic demands, whether or not it is capable of movement, its environment, and the structure and function of its digestive system. The digestive systems of herbivores contain microorganisms that assist in the digestion of cellulose. Carnivores are primarily adapted to consume animal flesh or fluids while omnivores eat plants as well as animals. After food has been ingested, some of the nutrients need to be broken down so that they can be absorbed by the cells of the digestive system.
