Question 7
Give an example of an organism that enters 'diapause' and why.
Answer
Bombyx mori (silk moth) is an insect that enters diapause. It enters into diapause due to some adverse environmental conditions such as drought, extreme temperature, reduced food availability; which, in turn, delays the overall development. The physiological and metabolic activities are also diminished at this particular time. Thus, it is a type of survival mechanism exhibited by the insect at the time of adversity.
