Because food webs in every type of ecosystem, from terrestrial to marine, begin with photosynthesis, chlorophyll can be considered a foundation for all life on Earth. The presence of chlorophyll is necessary for photosynthesis because it absorbs light energy and transports it to two different types of storage molecules. E. Leaves and green stems. An increase in chlorophyll B is an adaption to the shade, as it allows the plant to absorb a broader range of wavelengths of light. Chlorophyll is found in plants, algae, cyanobacteria, protists, and a few animals. Water splits into oxygen, hydrogen ions, and electrons to replace the lost electrons of photosystem II in the light- dependent reaction. The plant then converts glucose into ATP, which is then used to generate energy. This oxygen allows many non-plants to undergo respiration as well, thereby supporting life on Earth. Carbon dioxide enters the plant through structures called the stomata, which are usually found on the underside of the leaves. 33.
