Photosynthesis happens with plants on the earth’s surface where sunlight is abundant. Chemo synthesis can happen in the deep sea or places where there is an absence of sunlight. In both food webs, the primary sources both produce energy. A chemosynthetic food web often starts at a sea vent, with chemical energy. Photosynthetic plants get their energy from sunlight, while chemosynthetic bacteria will get their energy from sea vents. The difference is really in the beginning when it comes to where the primary producer gets their energy!
