Final answer:
Tropical rainforests have low soil nutrients due to heavy rainfall that leaches nutrients away, unlike temperate forests where soil is enriched by slowly decomposing leaf litter.
Step-by-step explanation:
The characteristic that is not typical of tropical rainforests is high soil nutrients. Tropical rainforests have a rapid cycle of organic material decomposition which contributes to a rich layer on the forest floor. However, heavy rainfall leads to quick leaching of nutrients, resulting in soils that are generally low in nutrients. Unlike temperate forests, where the leaf litter creates a thick layer that slowly decomposes and enriches the soil with inorganic and organic nutrients, tropical rainforest soils do not retain these nutrients due to the consistent and heavy rainfall.
Tropical rainforests are known for their dense vegetation, quick decomposition of organic material, and consistently high temperatures. However, the high rainfall in tropical rainforests quickly leaches nutrients from the soils, resulting in nutrient-poor soils.
