During chemosynthesis bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide dissolved in sea water.
Chemiosynthesis in the ocean floor.
The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
Photosynthesis gives off oxygen gas as a byproduct while chemosynthesis.
Back in 1977 a very interesting discovery was made on the deep ocean floor where no light penetrates.
However at hydrothermal vents in the deep ocean a unique ecosystem has evolved in the absence of sunlight and its source of energy is completely different.
Scientists later realized that bacteria were converting the toxic vent minerals into usable forms of energy through a process called chemosynthesis providing food for other vent organisms.
Hydrothermal vents are like geysers or hot springs on the ocean floor.
A hydrothermal vent is like a geyser on the ocean s floor.
Communities of creatures have adapted to survive in these inhospitable conditions and continue to thrive through the process of chemosynthesis.
Far below the ocean floor scientists have discovered a microbial community away from undersea vents beyond the reach of the sun beneath the seafloor there is an ecosystem of microbes living in.
Chemosynthesis occurs around the hydrothermal vents at deep levels of the ocean.
An entire ecosystem living without light or oxygen chemosynthesis flourishes beneath the ocean floor.

While most life on this planet requires sunlight to live there is an.
Chemosynthesis is the process by which certain microbes create energy by mediating chemical reactions.
Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent.
