I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.

Answer:
The Species Survival Plans are supposed to to help ensure the survival of selected species in zoos and aquariums, most of which are threatened or endangered in the wild.

They are all necessary for photosynthesis to occur.
Photosynthesis is the term for the process by which plants produce food and energy in the presence of some inorganic substances and solar energy.
<h3>What is the reason behind the above answer ?</h3>
The glass of water won't react when it's placed in the sun's rays.
One explanation for the response is: Water and ambient carbon will be the reactants in the experiment, which should produce glucose and oxygen in the presence of the sunbeam.
The true photosynthetic reaction also uses carbon dioxide and water as reactants, but chlorophyll is a plant pigment that is present during the reaction.
