Explanation:

The given statement is false because tortoise is an ectotherm which means they change their temperature according to the change in  external environment

The body temperature of ectotherms does not necessarily match the ambient temperature

For example, if a tortoise is basking in a sunny field, the solar radiation might raise its body temperature well above ambient, and the tortoise's low surface area/volume ratio would cause it to retain that heat for a long time
