In some areas of the world, deserts are expanding into places that were once forests. During this process, some of the forest trees will die off because of the change in climate.
But, some of the trees may survive this process. What adaptation would give a tree a chance to survive this environmental change?
A) The growth of limbs that are skinnier and longer.
B) The use of cones to protect and eventually spread seeds.
C) The type of root system that can grow deep into the ground.
D) Increased hardness of the wood in the tree that allows it to grow higher, and absorb more sunlight.
