Back in 2011, the U.S. Census Bureaupublished a report breaking down the median household net worth by age and in quintiles. Because I only think comparison is a valuable tool to get a very broad feel for where you stand, I've excluded the lowest and highest quintiles.
Plants Found in the Amazon. There are over 2,000 bromeliad species in the Amazon rainforest. The most common bromeliad species is the tropical fruit, pineapple. You will find a variety of colors like purple, blue, orange, and red in bromeliad plant species.
A tropical rain forest has more kinds of trees than any other area in the world. Scientists have counted about 100 to 300 species in one 2 1/2-acre (1-hectare) area in South America. Seventy percent of the plants in the rainforest are trees. About 1/4 of all the medicines we use come from rainforest plants.any kinds of trees that grow in the mountains of the Amazon rain forest do not grow in the lowlands of that same forest. Layers of the Rainforest There are four very distinct layers of trees in a tropical rain forest. These layers have been identified as the emergent, upper canopy, understory, and forest floor.
