What are the important differences in the overall metabolic needs of a fish and a turtle and the ability of their circulatory systems to meet those needs? Select all that apply. Fish are less able to meet their metabolic needs than are turtles. Fish have a two-chamber heart (one atrium and one ventricle) and turtles have a three-chambered heart (two atria and one ventricle). Turtles are endothermic and fish are ectothermic Blood flows directly to other organs after being oxygenated in turtles, but return to the heart after being oxygenated in fish. Turtles have a double,-circuit circulatory system whereas fish have a single circulatory system.
