SKETCHY SUNDAY: Phytoplankton
The word plankton is Greek for “wanderer” or “drifter,” which is exactly how these microscopic algae pass their days in the upper layer of the ocean. Just like terrestrial plants, they utilize sunlight to undergo photosynthesis and provide the base of the marine food web. Although you can’t normally see them without the help of a microscope, there are actually such a vast amount of tiny plants that 2/3 of all photosynthesis on Earth takes place in the oceans!
