Chemosynthesis

What is chemosynthesis?

• Where bacteria use light energy to make glucose.
• Where plants use light energy to make glucose
• Where bacteria use chemical reactions to make glucose

What is the source of energy for chemosynthesis

• Light energy
• Chemical energy
• Kinetic energy

What is often used as a reactant in chemosynthesis?

• Oxygen
• Glucose
• Carbon dioxide

What is the product of both photosynthesis and chemosynthesis

• Glucose
• Water
• Oxygen

Name two chemosynthetic bacteria.

• Sulfur bacteria and nitrogen bacteria
• Sulfur bacteria and hydrogen bacteria
• Sulfuric acid bacteria and nitrogen bacteria

Where are the places that sulfur bacteria live.

• Near deep sea volcanic vents and inside tube worms.  
• In soil and roots of some plants
• Near volcanic vents and in soil

What do we mean by a symbiotic or mutualistic relationship?

• Where 2 living organisms live close together and only 1 organism benefits, the other is harmed.
• Where 2 living organisms live close together and both organisms benefit.
• Where 2 living organisms live close together and one organism benefits and the other eventually dies.
