The graph below illustrates the changes in the body temperature of two animal A and B at different environmental temperatures. Study the graph carefully and use it to answer questions (a) to (c) (a) From the graph of the environmental to deductions on the effect of the environmental temperature on the body temperature of the animals indicated as (i) A (i) B (b) Suggest one way by which the animal indicated as B can maintain its body temperature or prevent its body from over-heating (c) Give one example each of an animal whose body temperature can be similarly affected by environmental temperatures cs (i) Animal A (ii) Animal B
Explanation
(a) The body temperature of animal A is constant and does not depend on the environmental temperature. Animal A is homoithermic. The body temperature of animal B increases as the environment. (a) temperature increases. Animal B is poikilothermic (b) Animal B can hibernate or aestivate (c) ()) Man, birds, cat (iü) Snake, lizard toad,
