Explanation:
The correct answer is option C, that is, have poor soils with little organic matter.
In the tropical rain forests, only a thin covering of decaying organic matter is present. The majority of the tropical rainforest soils are comparatively poor in nutrients. The torrential rains and millions of years of weathering have washed the majority of nutrients out of the soil.
In the tropical rain forests, the soils are generally poor in nutrients and all the nutrients are captivated in the living species. The soils in various regions of the tropical rain forests are laterite soils.
