The Rainforest

This climate is considered tropical wet with temperatures between 68°F to 93°F and an annual precipitation of 50-260 inches. There is often a short season of less rain, or sometimes in areas with monsoon seasons, a short period of no rain. The soil contains very little nutrients because the trees quickly absorb all the nutrition out of the ground. A great amount of sunlight reaches the upper canopies, but very little sunlight filters down to the understory and forest floor. These are all characteristics of the _______ biome.
a.
deciduous forest
b.
alpine forest
c.
rainforest
d.
savanna
