Question

All of these phrases describe a tropical rain forest except

• A. Nutrient rich soil
• B. Many arboreal plants and animals
• C. Canopy composed of many layers
• D. Broad-leaved evergreen trees

Answer 1

The correct option is A Nutrient rich soil

• Tropical rainforests are rainforests that occur in areas of tropical rainforest climate in which there is no dry season – all months have an average precipitation of at least 60 mm – and may also be referred to as lowland equatorial evergreen rainforest.
• True rainforests are typically found between 10 degrees north and south of the equator; they are a sub-set of the tropical forest biome that occurs roughly within the 28 degree latitudes.
• Soil types are highly variable in the tropics and are the result of a combination of several variables such as climate, vegetation, topographic position, parent material, and soil age.
• Most tropical soils are characterized by significant leaching and poor nutrients, however there are some areas that contain fertile soils.
• The physical properties of soil control the tree turnover rates whereas chemical properties such as available nitrogen and phosphorus control forest growth rates.
  

So the correct option is 'nutrient rich soil'.
