The correct option is A Only 1
Only a small amount of the food that a warm-blooded animal eats is converted into body mass. The rest is used to fuel a constant body temperature. A cold-blooded animal can convert much more of its food into body mass compared with a warm-blooded animal.
Being cold-blooded, however, also has its advantages. Cold-blooded animals require much less energy to survive than warm-blooded animals do. Mammals and birds require much more food and energy than do cold-blooded animals of the same weight. This is because in warm-blooded animals, the heat loss from their bodies is proportional to the surface area of their bodies, while the heat created by their bodies is proportional to their mass.
Another disadvantage to being warm-blooded is that warm-blooded bodies provide a nice warm environment for viruses, bacteria and parasites to live in. Mammals and birds tend to have more problems with these infections than do reptiles, whose constantly changing body temperatures make life more difficult for these invaders. However, an advantage of this is that mammals and birds have developed a stronger immune system than cold-blooded animals.
