Nutrition and Digestion
Identify the different modes of feeding mechanisms found in the Animal Kingdom, describe each and give 2 example animals for each mode.
Why do Cnidarians, Flatworms and Protists have simple or no extensively developed digestive system? (clue: mention their digestive structure and their mode of feeding)
What are the structural adaptations of snakes that allowed them to eat and digest a whole prey?
Why do insects of one species have a changing diet requirement during their life history?
Different birds have varying food habits, discuss the structural and physiological adaptations that allow them to process these foods.
What are the four stages of the digestive process, describe each stage/step and indicate what are the products/substances produced and their fate?
Discuss the role of the endocrine system in controlling digestion.

- 1. Summarize the different modes of feeding discussed in this module in a table below. Mode of feeding Food absorption through body exterior surface Phagocytosis (Endocytosis) Pinocytosis (Endocytosis) Filter feeding or suspension feeding Piercing and sucking (Fluid feeding) Cutting and licking (Fluid feeding) Seizing of prey Jaws, teeth, and beaks Toxins Herbivore and grazing Mechanism Example of animalarrow_forwardAn animal’s feeding adaptations are an integral part of its behavior and usually shape the appearance of the animal itself. Discuss contrasting feeding adaptations of carnivores and herbivores.arrow_forwardDescribe the main difference between the planarian and vertebrate digestive systems. Question 13 options: The planarian does not have digestive system. The planarian digestive system is a branching gut sac that only has one opening to the environment. The planarian digestive system has a body opening to the environment on both of its ends, but a vertebrate digestive system does not. The vertebrate digestive system does not have as many highly specialized organs as that of vertebrates.arrow_forward
