Trees like the mesquite tree have deeper roots than other desert plants. how are these roots an adaptation for survival in the desert ecosystem?

Explanation:

The desert is a biome which is associated with hot, dry enviornment. This biome receives very low annual rainfall. As a result of this the animals and plants experience scarcity of water.

The trees like mesquite trees have deep roots this will help in absorbing water from lower bottom of the accumulated water table. Thus this adaptation will help in survival of the trees.
