And darkling beetles catch moisture on their legs and then lift them into the air till the drops trickle down into their mouths.

(ii) How do mongooses kill snakes?

Ans: Mongooses kill snakes without getting hurt themselves. Their reactions are so fast that they dodge each time the snake strikes. They continually make a nuisance of themselves, and after a while, when the snake gets tired, they quickly dive in for the kill.

(iii) How does the hump of the camels help them to survive when there is no water?
