In photosynthesis, the electrons come from water and end up

it ends in the creation of oxygen from carbon dioxide

Explanation:

Photosynthesis occurs in two stages. The first, specifically luminous or photochemical, depends directly on the light received, the energy of the solar rays between the wavelengths corresponding to the 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 the energy is transmitted, generating molecules of ATP (Adenosine triphosphate) and NADPH (Nicotinamide adenine dinucleotide phosphate ). 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 resulted in a compound similar to sugar called glucose (C6 H12 O6).

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

the answer to this predicament is false, by friend, i had this on a quiz, and i got it wrong, so i learned it, cos i was gonna have it on a test, and i got it right

one would be wind another would be water density
