a. High levels of precipitation wash away nutrients
b. The soil type is unsuitable for nutrient retention
c. The rapid decomposition uses up all nutrients
d. Excessive sunlight depletes nutrients

Answer 1

Tropical rainforests are considered nutrient-poor primarily due to the rapid decomposition of organic matter and vegetation, which can result in nutrients being consumed quickly by plants. Therefore, the best answer to the question is:

c. The rapid decomposition uses up all nutrients
