AP BIOLOGY

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 primary soil orders found in tropical rainforests are Oxisols and Ultisols, which are soils rich in iron and aluminum oxides (red color) but with low natural fertility. The majority of temperate rainforests have been felled, and currently, this biome type occupies less than 0.3% of the Earth’s land surface.

Detailed explanation-3: -Beneath the emergent layer is the canopy, a deep layer of vegetation roughly 6 meters (20 feet) thick. The canopy’s dense network of leaves and branches forms a roof over the two remaining layers. The canopy blocks winds, rainfall, and sunlight, creating a humid, still, and dark environment below.

Detailed explanation-4: -Soil Composition: Since there is a tremendous amount and diversity of foliage in tropical rainforests, you might assume that rainforest soils are rich in nutrients. In fact, rainforest soils are nutrient-poor because nutrients are not stored in them for very long.

Detailed explanation-5: -The climatic conditions in which these forests have developed are characterised by average annual temperatures of about 27° C, average rainfall of about 200cm and permanently high humidity. These are the ideal conditions for lush plant growth.
