Which of the following adaptations help elephants to live in a tropical rainforest?

The elephant has adapted to the conditions of rainforests in many ways. 

• It uses its trunk as a nose to smell food from a long distance and also to bend high branches with leaves and pluck them for eating.
• Its tusks are modified teeth that it uses to tear the bark of trees for eating.
• Its large ears help it to hear even very soft sounds and also to keep cool in the hot and humid climate of the rainforest.
