- 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. (no plagiarism pls, thank u!)arrow_forwardQ1: What might happen to an anemone without a resident clownfish?
