EXAMPLE FROM PRACTICE
Algae plants are fed by sunlight so that they are able to grow and thereby produce nutrients. The chlorophyll, the green substance that gives the Plankton Algae a green color ensures that the process of photosynthesis proceeds well. After they are fully grown the effect of the light changes and accelerates the degradation process. Chlorophyll, which remains active even after the harvest, will completely burn without proper protection, as long as it remains in contact with sunlight.
