Tropical Rain Forests

	In the area between the Tropic of Cancer and the Tropic of Capricorn, the sun shines with little variance all year.  The result of this uniformity is a rather stable temperature and precipition system, with little fluxuation of either.  The tropical rain forest biome exists in this region, where the land and man permits it to.  Tropical rain forests are densely populated with many types of plants and animals.
	The temperature of a tropical rain forest usually varies only 5 degrees, between 78deg F and 83deg F in the course of a year.  This combined with the rather stable and constant rain fall, creates a year-long growing season.
