Diagrams given below represent hearts of three different animals. Observe it and answer the question.

Among these, which heart is helpful to the animals that require more energy? Why?

Text Solution

Verified by Experts

Heart shown in figure 2 is helpful to the animals that require more energy. This is because a four chambered heart keeps oxygenated and deoxygenated blood separate and no mixing occurs. This improves the efficiency of oxygen supply to body parts, i.e., oxygen is delivered in more quantity quickly and helps the animals to meet higher energy needs.
