Vertebrate Adaptions For Terrestrial LifeAP-Biology Essay on vertebrate structural adaptations for terrestrial life.The problems of survival of animals on land are very different fromthose of survival of animals in aquatic environment. Describe four problemsassociated with animal survival in terrestrial environments but non in aquaticenvironments. For each problem, explain a physiological of structural solution.Four problems faced by animals on land are breathing (respiration), pee conservation in excretions, successful reproduction, and the producing anegg which can survive outside of the water.All animals need to respire, but I have no idea why. by chance you wouldlike to answer that? Aquatic animals use gills, which are outgrowths from thebody which increase surface area over which gas exchange can occur. Inside thegills of aquatic animals, the circulatory system removes oxygen, and deliverswaste carbon dioxide. Land vertebrates have developed a different approach tothe problem of gas exchange, as water is not present in all of the terrestrialenvironment. Terrestrial vertebrates have developed lungs to solve this problem.Air enters through the nasal passages, or the mouth, passes through the trachea,then branches off-key at the two bronchi, and goes through many branching passagescalled bronchioles, which end in alveoli. Alveoli are sack-like structures wherethe circulatory system meets the respiratory system.S...
