What is a tube worm?
A worm that lives at the bottom of the sea near hydrothermal vents.
Name 2 types of chemosynthetic bacteria
sulfur bacteria
nitrogen bacteria
What is usually a reactant of chemosynthesis?
carbon dioxide
Bacteria that produce glucose via chemosynthesis are called…
chemosynthetic bacteria
Which type of chemosynthetic bacteria are usually found in soil and the roots of plants?
nitrogen bacteria
Chemosynthesis requires energy to produce glucose. Where does this energy come from?
chemical reactions
What sort of relationship do tube worms and sulfur bacteria have?
A symbiotic or mutualistic relationship
Sulfur bacteria live inside tube worms. Why does this benefit both organisms?
It is a safe place for bacteria to live.
The bacteria produce glucose for the tube worms
Which type of chemosynthetic bacteria are usually found near deep sea volcanic vents?
sulfur bacteria
How do sulfur bacteria produce glucose?
They react carbon dioxide and water from the sea with hydrogen sulfide from hydrothermal vents.
They also use some compounds provided by tube worms.
What is the main product of chemosynthesis?
glucose
What type of nutrient is glucose?
A carbohydrate
What is chemosynthesis?
When an organism uses chemical reactions to produce glucose.
Organisms use glucose (carbohydrate) for…
energy
