Solar energy mainly controls the water consumption of plants through the transpiration process. Water acts as an absorbent material in the infrared region, and plant pigments other than water acquire energy from two regions of the visible spectrum.
The soil has the function of anchoring and providing conditions for the development of plants, which obtain the nutrients necessary to carry out their processes. It also provides the conditions for the development of various biological organisms, such as viruses, bacteria, fungi, algae, helminths, mites, worms, nematodes, ants and plant roots.
