When large pieces of the Earth's outer layer move slowly by plate tectonics, surface features, such as mountains, earthquakes and volcanoes, are formed
Water. the only 4 macromolecules are nucleic acid, carbohydrate, lipids, and protein
All they need for their living is carbondioxide in air ,water and some nutrients .so basically their roots are responsible for collection of water which contains life giving nutrients .but we take food as a solid substance which hasto be converted into energy
The root system, the roots can store energy, anchor the plant to the ground and other surfaces, and they also adsorb and "drink" nutrients and vitamins from the soil. Remember to check yourself.
Hope this helps :)
