Question

Which deduction can be made by analysing the following graph?

• A. A is an endotherm and B is an ectotherm
• B. A is an ectotherm and B is an endotherm
• C. The body temperature of ectothermic animals increases during the day.
• D. The environmental temperature has no influence on endothermic animals.

Answer 1

The correct option is A A is an endotherm and B is an ectotherm

From the graph given, it can be interpreted that animal A is an endotherm, that is, it maintains its internal body temperature constant, while animal B is an ectotherm or a cold-blooded animal whose body temperature varies with that of the environment.

So, the correct answer is 'A is an endotherm and B is an ectotherm'.
