2.5 Adaptations for Nutrition
You should be prepared to discuss....
(a) The differences between autotrophic and heterotrophic methods of nutrition. The principles of saprotrophic nutrition in Fungi. Secretion of enzymes, external digestion, absorption by diffusion.
(b) Processing food in a tube gut. Ingestion, digestion, absorption and egestion.
(c) The layered structure of the wall of mammalian gut. Regional specialisations of the mammalian gut. Functions of stomach, small intestine and colon.
(d) Adaptations to different diets. Comparison of dentition in a carnivore and a grazing herbivore. Adaptations of herbivore gut to a high cellulose diet. Comparison of the gut regions of herbivore and a ruminant.
(e) The principles of parasitism as shown by a gut parasite e.g Taenia solium or Echinococcus granulosis.
