During the light independent reaction of photosynthesis light energy is converted to the energy currency of all cells this energy carrying molecule is needed to produce glucose this molecule is

Light-Dependent Reactions of Photosynthesis. The first major set of processes in photosynthesis, in which light energy is initially converted into chemical energy as ATP and NADPH, takes place across the chloroplast thylakoid membranes, between the chloroplast stroma and the thylakoid space.

These electrons move through structures in chloroplasts and by chemiosmosis, make ATP. The hydrogen is converted to NADPH which is then used in the light-independent reactions. Oxygen diffuses out of the plant as a waste product of photosynthesis. This all happens in the grana thylakoid of chloroplasts.

There are several ways in which human economics and ecology are linked, but perhaps the most prominent way is that humans tear down forests for fuel and other reasons, which disrupts the environment of many organisms.
