Contrast the feeding strategies and the structure of the digestive systems of each of the following (Demosponge;a sea anemone - class Anthozoan; and earthworm). In discussing the structure analyze the efficiency of each system and what constraints the structure of the system places on the type of food that can be fed on.

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.

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.
