Where are tropical rainforests?
The bougainvillea has hooks that connect to their vines that they can connect to other plants to get sunlight. Also, they can grow in full sunlight to semi-shade and they have become a house plant so they can survive there too.
The Bambusa tulda, or Bengal Bamboo, can live in weather from 40 to 100 fahrenheit. This allows it to adapt to nearly any environment in that range that is moist/wet.
The coconut tree lives in hot areas that are frost free. They need to be near the sea so it can be in a moist environment.
Bromeliads can grow on almost anything, the ground, rocks, and other plants and trees. They also suck nutrients and moisture out of the air so they can probably live almost anywhere that is at least a little bit moist.
Orchids can grow underground, on rocks, in the soil, and on other plants and trees. They also suck moisture and nutrients out of the air. Some self-pollinate but others need insects to pollinate them. All orchids need to live in an area where mycorrhizae fungi grow so they can absorb water.
The sloth produces an algae on their coat and they eat that and it provides camouflage. It eats leaves, bark, buds, and fruit so it has to live an a place where things can grow. They have curled fingers so they can hold on to branches.
The boa constrictor's tongue can smell to locate its prey and its mouth can sense heat to locate its prey.
The orangutan has strong arms for traveling, curved feet for extra balance, and opposable thumbs for grabbing branches.
The chimpanzee makes a nest of leaves high in the trees to avoid their predators and they use stone and wood to open nuts.
The King Cobra spits venom into its predator's eyes when it feels threatened. The venom is deadly when it gets in the blood stream. It also spits at its prey before it can run away.
When humans cut down trees and plants there becomes a build up in carbon dioxide. With no trees or plants to turn carbon dioxide into oxygen, the co2 just stays there. More and more co2 builds up and it can eventually turn lethal to the animals. Also with less plants, there is less for the animals to eat. The animals go extinct and suddenly there is a major hole in the food chain. Carnivores can no longer prey on the animals they had been eating so they can go extinct too. Eventually, with less animals in the rainforests, there is less for humans too eat too. That would be a disaster.
About 1/4 of medicine comes from plants in a rainforest. With humans cutting down those plants, we can use them as medicine, but that would be a one and done scenario. We would cut down call the plants we need, but then we wouldn't have any of that plant left so we wouldn't be able to make that medicine again. We need to stop cutting down the rainforests so we can preserve critical plants that we need for medicine.
