Answer 1

The main strategy birds use to maintain their body temperature is A- using energy from food to keep their bodies warm.

Birds are endothermic, which means they generate their own body heat. They have a high metabolic rate and generate heat by breaking down food. This heat is then used to maintain their body temperature. To conserve this heat, birds have adaptations such as feathers, which provide insulation, and a high surface-to-volume ratio, which reduces heat loss. Birds can also fluff up their feathers to create air pockets that trap heat close to their bodies.
