Natural Vegetation And Wildlife - Class 7 Geography - Extra Questions

How do trees in the Tropical desert forests adapt themselves to the dry climate?

Many desert plants have vast root systems, capable of reaching deep, otherwise unusable water supplies under the dry soil.  Wax coatings on leaves prevent water loss through evaporation, which in the hot desert can cause loss of water from both the surface and the inside of the leaves. Leaves are also smaller on desert plants, further reducing the possibility for water loss. Many plants in the desert conserve water by not having any leaves at all.
