Question

Cite any two examples to explain how rainfall affects the natural vegetation of a place.

Answer 1

Rainfall influence the natural vegetation in terms of the size and structural shape of the plants. Generally, the place where precipitation is high, for example, in a tropical rainforest, plants are evergreen and have drip tips to allow rainwater to flow off the plant. Plants will also have a waxy cuticle to prevent water loss by transpiration due to high temperatures. for example Palm tree, Kapkon tree of Amazon rainforest.

Whereas, in dry places, for example, in a desert, plants will have long roots that can grow deep underground. They will also have succulent leaves or needle-like leaves to prevent excessive water loss by transpiration during the day. The size of the plant also varies with the vegetation area. In the desert (hot region), plants do not grow as tall as those found in tropical forests have an abundant supply of sunlight, water, and nutrition, for example, Palo verde and cactus of California desert.
