Organisms that use photosynthesis combine energy from sunlight with carbon to make sugar, forming the basis of most food chains.
The Abyssal Zone is one of the many benthic zones we have highlighted to describe the deep oceans. This particular zone is found at depths of 2, to 6, meters 6, to 19, feet and stays in perpetual darkness.
Photosynthesis and chemosynthesis both contain water and oxygen in the reactions involved. Photosynthesis’s chemical formula is 6H2O+6CO2—-C6H12O6+6O2. The chemical formula for chemosynthesis is 6CO 2 +6H 2 . Scientists hypothesize that chemosynthesis could be responsible for life below the surface of Mars or on Jupiter's moon, Europa, which is thought to be liquid water underneath a frozen surface. If true, the first life discovered beyond Earth would most likely be simple bacteria, such as those living inside the gut of tube worms. Chemosynthesis in the Classroom Pupils observe the development of chemosynthesis in bacterial communities. In this bacteria lesson students explore that chemosynthesis is and how it is relevant to biological communities.
Just below the abyssal zone and extending to the bottoms of the deepest trenches is the hadal zone. Very few animals exist in this habitat.
Just above the abyssal zone is the bathyal zone and just above that the photic zone where much of the oceans life exists. Pressure Because water pressure increases one atmosphere every 33 feet in depth, animals in the abyssal zone must be able to withstand tremendous amounts of pressure.
This pressure makes it very difficult for humans to explore the deep ocean. For example, the deep Marianas trench off of the Philipeans is almost completely unexplored. The only submersable that has made these depths is the French bathyscaph Trieste.
Animals Animals in the deep ocean are unique. Because food is scarce in this zone most animals have large gaps to injest any possible food.
A great example of this is the deep-sea anglerfish. In many ways the deep sea is about eat or be eaten. Other deep sea animals include the infamous giant squid, black swallower, tripod fish. Chemosynthesis, the basis of life in the deep sea A remarkable find when submersables starting probing the deep sea was the presence of extraordinary abundance of life around mid-ocean vents.
Previously, scientists believed that little lived at these emense depths. The only food that would have been avaliable was through dead animals floating down from the surface waters. So what was this abundance sustaining itself on? The answer came from the discovery that bacteria in the vents were able to convert hydrogen sulfide coming out of the vents into energy.
These bacteria then supported large tube worms, crustaceans, and multitudes of other organisms. The most amazing part of this find was that science had found organisms whose primary energy source was not the sun.
It was previously thought that life depended on photosynthesis, converting sunlight to energy. This new find spured questions about how life arose on planet earth.Learn chemosynthesis with free interactive flashcards.

Consumers, or heterotrophs, get organic molecules by eating other organisms. A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
