(i) Desert animals cannot survive without water. They find different ways of coping with the harsh desert conditions. For example, gerbils spend the hottest part of the day in cool underground burrows. And darkling beetles catch moisture on their legs and then lift them into the air till the drops trickle down into their mouths.
(ii) 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.

Solution B
All animals in forests and deserts struggle to survive in harsh conditions. Though most of the animals are harmless, some are dangerous when threatened. If an intruder is noticed, they attack or bite to save themselves. They struggle continually for food and water. Some animals are called predators because they prey on other animals.
