They grow close to the ground because they need a source of nutrients which is given of by the soil (in the ground;). yet some plants don't get all the thing they need to stay alive, like sunlight in rainforest's. The tall canopy blocks the sunlight for all the plants that live on the ground and that is why not alot of plants live on the ground in rainforest's.

enough where the roots can stretch out
Why might plants grow best in soils with air spaces?
this is so because air spaces in soil allow water to reach the plant's roots faster and air to circulate through out the plant. Also the airspaces allow the plant roots to grow deep within the earth's surface.
Why does soil need air?
Air is needed in soil so it can help the roots grow. The roots need a good supply of air or else they will die. Over watering the plant can remove the air from the soil, making it hard for the plant to grow. the soil needs air so that the water contant will incrace.

How are plants roots adopted to take in water from the soil?
with taproots, the primary and secondary roots grow long. they can reach a deep water source. with fibrous roots, the fine, numerous roots allow fast absorption of water near the soil surface.
What are 2 adaptations in root system of desert plants?
one common adaptation of the root system of a desert plant is to grow very deep in the soil to collect moisture from depths that has not evaporated. another is to grow roots close to the surface but spread far out to collect as much moisture as possible from a larger surface area
What Usually obtains water close to the soil surface?
