Correct Answer: (i) hot and humid.


Tropical rainforests are thick forests that grow near both sides of the equator of the earth. The countries where tropical rainforests are found i.e. India, Malaysia, Indonesia, Brazil, Republic of Congo, Kenya, Uganda, and Nigeria.

Usually, the tropical rainforest is a darker, stiller, and more humid area that is a few meters below the canopy. Plants like palms and philodendrons are much shorter and have bigger leaves than the plants that make up most of the canopy. Large leaves on plants in the understory catch the little light that gets through the dense canopy.

The plants, like the Heliconia, native to the Americas and the South Pacific, often have big, easy-to-see flowers. Some of them, like orchids, have a strong smell. Even when there isn't much light in the understory, pollinators are drawn to these things.

There are many reasons for the animals to choose the rainforest to live as many animals use the dim lighting to hide. People might mistake the spots on a jaguar, which lives in the rainforests of Central and South America, for leaves or bits of light. In the Congo rainforest, the green mamba, one of the most dangerous snakes in the world, blends in with the plants as it climbs up branches. Many bats, birds, and bugs like the open space that the understory gives them. Amphibians, like brightly colored tree frogs, do well in humid places because their skin stays moist.

Some tropical rainforests have rivers that run through them. These rivers create strange freshwater habitats on the forest floor. The boto, also called the pink river dolphin, lives in the Amazon River. It is one of the few dolphin species that live in freshwater. Black caimans, which are big reptiles related to alligators, live in the Amazon. The Nile crocodile, which is related to caimans and lives in the Congo River, lives in the Amazon.
