Physiology in biological sciences (cid:862)the study of ho(cid:449) a(cid:374)i(cid:373)als (cid:449)ork(cid:863) Study of how structures and functions of the body work together to sloe got behavioural responses to the environment. Coyote (carnivore) has a relatively smaller intestinal tract. Koala (herbivore) have a relatively larger intestinal tract an much larger cecum filled with gut bacteria that can break down cellulose. Their diet includes foods that are harder to break down (eucalyptus) Shaped and limited by chemical and physical properties of the environment and evolutionary relationships. What kind of challenges do animals living in aquatic environments share: wet all o the time. Less light: more dense, more viscous (but body supported by buoyancy, oxygen hard to extract. What kind of challenges do animals living in terrestrial environments share: dry all of the time, more light. Less dense, less viscous (no body support by buoyancy: oxygen easier to extract, no suspended nutrients.
