Which of the statements below is valid?
- The bird’s blood was always warmer than that of the lizard
- The body temperature of the bird varied less than that of the lizard during changes in environmental temperature
-
The body temperature of the bird remained constant despite changes in environmental temperature
- The body temperature of the lizard was always close to that of the environmental temperature
The correct answer is: C
Explanation
From the graph of the body temperature of a lizard and a bird under artificial conditions. It can deduced that;
* Lizard
- It is a poikilothermic organism
- Its body temperature varies with the temperature of the environment
- The lizard needs to change to the environment temperature so that it can survive.
* Bird
- It is a homothermic organism
- Its body temperature is always constant to the environment
- The environment temperature those not affect the temperature of the body of the bird
