<span>During the Calvin cycle, carbon dioxide is reduced to drive the formation of sugars.
During the process of photosynthesis, a set of chemical reaction that occurs in the chloroplast is known as the Calvin cycle, which is light independent.
Photosynthesis reaction can be divided into two stages that are the light reaction and the Calvin cycle, in the first stage light energy converted to the chemical energy and the second stage use the products of light reaction to produce sugar.

Yes because without producers the whole thing Dallas apart. Without leaves that get their energy from the sun insects wouldn’t be able to eat this reducing their population, then frogs and mice wouldn’t be able to survive without their main source of food , then snakes wouldn’t be able to eat, then eagles wouldn’t be able to eat and so on.
