Photosynthesis and Respiration
Life without the use of Photosynthesis
Made By: Sierra and Nicole
How does each organism survive and how do they get energy? What are the chemical interactions?
Formula For Chemosynthesis
Carbon Dioxide+Water+Hydrogen Sulphide---->Sugar+Sulphur Compounds
Primary Producers
Arcobacter Sulfidicus
Venenivibrio Stagnipumantis (VS)
Beggiatoa
Primary Consumers
Giant Tube Worm
Giant Clam
Vent Amphipod
Diagram of Energy Conversions
Life at the vent area is intimately connected to the vent fluid. Seawater slips through the porous crust of the seafloor. It is then heated and reacts with the chemicals in the rock. The heat is believed to come from the magma chamber underneath the floor. This heated water rises through the crust, seeking a way to get to the surface. This is a hydrothermal vent. Underneath the vents and under the seafloor, it is possible that subsurface mini-environments exist. All vent microbes rely on chemosynthesis as their source instead of photosynthesis, because it is dark around the environment.
Diagram of Mussels during Chemosynthesis
Mussels and tubeworms around a vent are releasing hydrogen sulfide gas. The chemical equation given here for chemosynthesis is just one of a number of possibilities.
Carbon Dioxide + Water + Hydrogen Sulfide = Sugar + Sulfur Compunds
Interdependence between organisims in relationship to energy transfer.
Giant tube worms and Giant clams form symbiotic relationships with chemosynthetic bacteria. The bacteria thrives inside the animal’s tissues and it provides the animal a built-in food supply. Since tube worms have no mouth they nutrients are absorbed directly into the tissues.
Some vent animals like clams and mussels feed directly on bacteria and octopi prey of those that eat bacteria.
