Answer :
The appropriate answer is B. Throughfall. These nutrients are transported via the process of throughfall where rain flows from leaves to the ground. Rainforests receive high annual rainfall. The leaves are also designed to funnel water to the ground soon after a shower. Leaves are equipped with drip tips to allow water to roll of leaves easily. Any particles deposited on leaves are going to be washed to the forest floor by frequent rainfall that occurs here.
The right answer is B) through fall.
Nature is decidedly well done, and fall leaves in autumn is the perfect illustration! Although most trees lose their leaves in autumn, it is certainly not by caprice but by necessity. On the one hand, the mechanism of the fall of the leaves is vital for the tree which thus implements a measure of natural protection against the great colds to come. On the other hand, fallen leaves will be used by insects and microorganisms to feed on them and transform them into inorganic matter.
