    If a tropical rainforest is removed, it does not regenerate quickly as compared to a tropical deciduous forest. This is because

    A)  The soil of rainforests is deficient in nutrients.

    B)  Propagates of the trees in a rainforest have poor viability.

    C)  The rain forest species are slow growing.

    D)  Exotic species invade the fertile soil of rain forest.

    Correct Answer: A

    Solution :

    [a] Most tropical rainforest soils relatively poor in nutrients. Millions of years of weathering and torrential rains have washed most of the nutrients out of the soil. More recent volcanic soils, however, can be very fertile. Tropical rain forest soils contain less organic matter than temperate forests and most of the available nutrients are found in the living plant and animal material. Nutrients in the soil are often in forms that are not accessible by plants.
