biodiversity/evolution
a example of adaptation in the tropical rain forest is sloths climbing trees to escape predators. A example of natural selection in the rain forest is a fire stating by the temperature of the forest.the changes that happened during natural selection in the forest when a fire stars are that the floor burns and the grass and trees eventually grow back. the animals affect the rain forest by if there is to many animals then they will eat all the stuff,and it will be over polluted.the range of tolerance is each ecosystems populations ability to adjust to variations in its physical and chemical environment.a gorillas population in the tropical rain forest is 5,000-15,000.
