Their guts also tend to be lengthy and the food takes a long time to pass through it.Įating plants have other advantages. This is why herbivores have teeth that are adapted to crush and grind. To give the micro-organisms access to the cellulose molecules, the plant cell walls need to be broken down. Herbivores like cows, horses and rabbits typically spend much of their day feeding. Plants are a primary pure and good source of nutrients, however they aren't digested very easily and therefore herbivores have to eat large quantities of food to obtain all they require. These non-ruminant herbivores include the horse, rabbit and rat. The second group has an enlarged large intestine and caecum, called a functional caecum, occupied by cellulose digesting micro-organisms. The first, ruminants like cattle, sheep and goats, house these bacteria in a special compartment in the enlarged stomach called the rumen. Therefore herbivores employ micro-organisms to do the job for them. While no animal produces the digestive enzymes to break down the large cellulose molecules in the plant cell walls, micro-organisms' like bacteria, on the other hand, can break them down. Some animals (herbivores) eat plants some (carnivores) eat the herbivores. Animals rely on these ready-made organic molecules to supply them with their food. Plant cells are made of organic molecules using energy from the sun. the parts of the gut in the order in which the food passes down.the characteristics, advantages and disadvantages of a herbivorous, carnivorous and omnivorous diet.what is meant by the terms: ingestion, digestion, absorption, assimilation, egestion, peristalsis and chyme.After completing this section, you should know:
