False
Fill in the blank: The primary reason for the low nutrient levels in tropical rainforest soils is __________.
rapid decomposition and leaching
What is the effect of heavy rainfall on the soils in tropical rainforests?
It leads to leaching of nutrients and minerals.
What is nutrient cycling?
The process by which nutrients are transferred between living organisms and the environment.
True or False: Nutrient cycling in tropical rainforests is rapid due to high temperatures and humidity.
True
