Pacific Ring of Fire Expedition

Pacific Ring of Fire Expedition. Photosynthetic green and red algae is growing on the same rocks as chemosynthetic bacterial mat near the top of East Diamante volcano. Usually, these two life forms are not found together because one depends on the sun for energy and the other on chemical energy from deepsea hydr othermal vents. Here, however, submarine volcanoes come close to the surface.
