Question

All of these phrases describe 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

Aboral plant and animals, canopy and evergreen trees are characteristic features of tropical rainforest. This happens as the climate does not go dry at any time of year.

Complete answer:
Rainforests occurring in areas where the climate provides optimal conditions for tropical rainforest with no dry season are called tropical rainforest. Typically, true rainforests are present between 10 degrees north and south of the equator. They are considered as the tropical forest biome. Such biomes occur roughly within the 28-degree latitudes. Tropical rainforests are a type of tropical moist broadleaf or tropical rain forest within the World Wildlife Fund's biome classification. The extensive seasonal tropical forests are also included in this. Tropical rainforests are characterized as two types; hot and wet. Mean monthly temperatures exceed 18 °C all around the year. Average annual rainfall typically lies between 1,750 mm and 3,000 mm but it is at least 1,680 mm and can exceed 10 m. Due to such high levels of precipitation, leaching of soluble nutrients occur in the ground, which makes the soil poor.

Thus, the correct answer is A. Nutrient rich soil.

Note: Tropical rain forests on an average experience precipitation of at least 60 mm therefore are also referred to as lowland equatorial evergreen rainforest. Soil types are considerably variable and are formed by a combination of effects due to climate, topographic position, vegetation, parent material, and soil age. Tropical soils undergo significant leaching and are poor in nutrients, some fertile land may be present in several areas.
