The image below shows the placement of all ecosystems in Biosphere 2. In the Biosphere 2 rainforest, the climate changes in day length. There are also shorter winter days and the temperature ranges on a daily and annual basis. This is not consistent with a real rainforest because ordinarily, the winter days are longer and the temperature does not vary as much. Animal life is also an important factor in the rainforest.
Animals are necessary to define a food web.
Though real rainforests include such animals as monkeys, flying fish, and parrots, there is no mention of animal life in the Biosphere 2 rainforest. The Macaw is one animal found in a real rainforest. A positive aspect of the Biosphere 2 rainforest is that it is, for the most part, accurate with the features of a real rainforest. Because of this, the rainforest biome is a great help in studying the plant life and nutrient cycles of a rainforest, among other things. The closer it is to the reality, the more accurate one's studies will be.
