Answer: The adaptations like paddy feet and fur on the outer body is an adaptation for very cold place but not for the rain forest.
Explanation: If the outer body of the organism is made of fur then it will protect the inside body from cold and will provide warmth.
But if the body will have adaptation like fur in the rain forest then it will make the organism wet so there will be no use of fur on the outer surface of the organism.
The adaptation like camouflage will help the organism in the rainforest so that it can hide themselves from predators in the forest.
