Yes, while the tropical rain forest has more types of trees than anywhere else in the world, there are actually three layers of canopy: see the link, please...
they grow to about 164 feet
Trees in the Amazon rainforest all tend to be tall. Some of these trees reach heights of 130 meters high. Very few trees are small.
because they want to get as much sunlight as possible and they have to compete with all the trees around them
so they can grow past the canopy and see the light because the canopy blocks out all the light :)
