Answer:

Explanation:
The biome that has infertile soil, principally oxisols, to which the vegetation <span>has roots systems that capture nutrients from litter decay, is the tropical rainforest.
Soil types are highly variable in the tropics and are the result of a combination of several elements or variables which includes climate, vegetation, topographic position, parent material and also the soil age. Most of the tropical soils are described by leaching and poor nutrients. It also has two classifications: namely the ultisols and oxisols. Ultisols are known as well-weathered, acidic red clays soils. They are deficient primarily in major nutrients such as potassium and calcium. Oxisols are also an acidic type of tropical soil. However, they are well drained compared to the ultisols.

I might be wrong but I think C ( what the wave it traveling through). I think C because a wave medium is the substance that carries a wave (or disturbance) from one location to another. The wave medium is not the wave itself and it doesn’t make the wave. It just Carries or transports the wave from its source to other locations.
