Question

how does organismal behavior demonstrate an emergent property of an organism's physiology?

Answer 1

Physiology is concerned with how an organism functions, as opposed to anatomy which is more concerned with its structure. So as an example, fish gills exchange oxygen with the environment, so a behavior that results from this might be that it needs to swim in order to maintain a flow of oxygen for respiration.

Answer 2

in addition, think along the reproductive behaviors of many species, particularly the difference between invertebrates and vertebrates.
