What is the natural process that converts radiant energy into chemical energy called?

Photosynthesis

Explanation:

Photosynthesis occurs in two stages. The first, called luminous or photochemical, depends directly on the light received, the energy of the solar rays between the wavelengths corresponding to violet, blue, orange and red light. This energy produces the excitation of electrons and causes the breakdown of water molecules, so that oxygen is released and the rest of energy is transmitted, generating ATP (Adenosine triphosphate) and NADPH (Nicotinamide adenine dinucleotide phosphate) molecules. . These components are used in the next stage, which is known as the dark phase because it does not depend directly on light. This second stage develops in the stroma, the internal aqueous space of the chloroplast. There the energy in the form of ATP and NADPH produced in the photodependent phase is used to fix the carbon dioxide as organic carbon, by means of the Calvin Cycle. This consists of a series of chemical reactions in which phosphoacylglycerides are produced with which the plant cell produces nutrients. The process results in a sugar-like compound called glucose (C6 H12 O6).

The phenomenon of photosynthesis carried out by all terrestrial and aquatic plants on the planet, and also algae and some bacteria, is essential for life on Earth. By absorbing solar energy and carbon dioxide and returning oxygen and carbohydrates, the plant kingdom becomes a fundamental part of the natural cycles of energy, carbon and oxygen.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
