Vertebrate Adaptations For Terrestrial Life
AP-Biology Essay on vertebrate structural adaptations for terrestrial life.
(From an actual past AP-BIOLOGY test)
The problems of survival of animals on land are very different from
those of survival of animals in aquatic environment. Describe four problems
associated with animal survival in terrestrial environments but not in aquatic
environments. For each problem, explain a physiological of structural solution.
Four problems faced by animals on land are breathing (respiration),
water conservation in excretions, successful reproduction, and the producing an
egg which can survive outside of the water.
All animals need to respire, but I have no idea why. Maybe you would
like to answer that? Aquatic animals use gills, which are outgrowths from the
body which increase surface area over which gas exchange can occur. Inside the
gills of aquatic animals, the circulatory system removes oxygen, and delivers
waste carbon dioxide. Land......
