Why is there so little life at the bottom of the ocean?
The pressure is too high for organisms to survive
There is little food there
The soil is poor quality
It is too dark for organisms to find mates
How do organisms get their energy in the deep sea around hydrothermal vents? (Name the process, organisms involved, and the name of the chemical compound)
sun, bacteria, hydrogen sulfide
chemosynthesis, mutualism, chlorine
chemosynthesis, bacteria, hydrogen sulfide
photosynthesis, bacteria, hydroxide
In the upper zone of the Ocean is where the primary producers of the ocean lives here they use
Photosynthesis
Chemosynthesis
Process by which producers convert light energy from the sun into chemical energy in the form of glucose (Sugars)
Photosynthesis
Chemosynthesis
Chlorophyll Plastic
Enzymic
Light-capturing pigment found in the chloroplast.
Chlorophyll
Photosynthesis
Enzymes
organelles
Needed to catalyze (Increases the rate of reaction without undergoing chemical change) the reaction.
Chlorophyll
Photosynthesis
Enzymes
organelles
In the deep ocean sea floor where there are hydrothermal vents, (opening in the sea floor out of which heated mineral rich water flows) this takes place by bacteria.
Photosynthesis
Chemosynthesis
_________________ are eaten by organisms such as shrimp and form the first step in a series of deep ocean food chains.
Bacteria
Small Fish
Whales
Humans
Process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight.
Photosynthesis
Chemosynthesis
Chlorophyll Plastic
Enzymic
Both Photosynthesis and Chemosynthesis
Use Carbon Dioxide
Require a source of energy to activate the reaction
Both produce Glucose (Sugars) for energy
All of these
Photosynthesis
Requires Hydrogen Sulfide
Requires Light Energy
Produces water and sulfur
Energy for the reaction comes from breakdown of hydrogen sulfide molecules
Chemosynthesis
Requires Water
Produces Oxygen
Requires Light Energy
Requires Hydrogen Sulfide

Another name for the Aleutian Islands
Species of squid that let out white ink
Hydrothermal vents
