Detailed explanation-1: -The high temperature and moisture of tropical rainforests cause dead organic matter in the soil to decompose more quickly than in other climates, thus releasing and losing its nutrients rapidly. The high volume of rain in tropical rainforests washes nutrients out of the soil more quickly than in other climates.

Detailed explanation-2: -The amazing thing is that the soil is as poor in nutrients as the vegetation is rich. The humus layer, which is that dark, organic stuff in the soil that develops when plants or animal matter break down, is minimal nearly everywhere. The soil in the Amazon rainforest is the poorest and most infertile in the world.

Detailed explanation-3: -The soil found in the forest ecosystem of the temperate deciduous forest biome is rich in nutrients because of decaying material such as fallen leaves that is broken down into rich organic material called humus. This humus rich soil is also great at holding water, making it available for plant use.

Detailed explanation-4: -Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.

Detailed explanation-5: -Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons.
