A deep sea community is any community of organisms associated by a shared habitat in chemosynthesis communities deep sea. The limited amount of light, however, can still allow organisms to see, and creatures with a sensitive vision can chemosynthesis communities prey, communicate, and orientate themselves using their sight.

And as their roots grow, they also may fill in the cracks in the rock on which they live, thus preventing the chemicals from making it to the sediment surface. The chemosynthesis communities amount of light, however, can still allow organisms to see, and creatures with a sensitive vision chemosynthesis communities detect prey, communicate, and orientate themselves using their sight.

Once the supply of chemicals stops, the bacteria die and the rest of the fauna either migrates or perishes.

The presence of the mussels Chemosynthesis communities childressi in the center of the bush means that methane is seeping just below.

It is possible that all of the bacteria inside the tubeworm render it too toxic for the predators to digest. Photosynthesis occurs in plants and some bacteria, wherever there is sufficient sunlight — on land, in shallow water, even inside and below clear ice.

From this simple reaction, an entire ecosystem grows. The bacteria convert the chemicals to organic matter and share the excess with the tube worms. And as their roots grow, they also may fill in the cracks in the rock on which they live, thus preventing the chemicals from making it to the sediment surface.

When tubeworm bushes are young, only endemic species of animals can colonize them. Nereus reached a depth of 10, meters at the Challenger Deep on May 31, In , researchers reported their discovery of bacteria living in the rock of the oceanic crust below the thick layers of sediment, and apart from the hydrothermal vents that form along the edges of the tectonic plates. Adaptation to Exotic Environments , Springer, pp.

Additional research expeditions in the area revealed other types of communities, including a few types of mobile clams and extensive mussel beds.
