The passage describes chemosynthetic bacteria, and the diagram models a basic food web.
Deep below the surface of the ocean are communities that thrive without even a trace of sunlight. The trick is something called chemosynthetic bacteria. These bacteria are released by hydrothermal vents on the ocean floor, which are vents that are very hot and are able to chemically produce their own energy. Very small organisms, like tube worms, shrimp, mussels and clams, come to feed on the bacteria from the vents. Then, there are crabs that eat the bacteria but also eat shrimp, mussels, clams, and tube worms. Last, there is the vent octopus, which will eat everything.
