Explain how it is possible for plants like air plants and water lilies to grow just from air and water and not need to be planted in soil to grow.

Explanation:

Many plants don't need soil to grow. They only need soil for the nutrients. Water also has those nutrients, but plants need soil when they don't have enough nutrients. (For example, beans and dandelions.) Air plants get their nutrients by attaching themselves to a larger plant and feeding off that plant's nutrients. (For example, a bromeliad attached to a tree.)
