Hydrothermal Vents Flashcards
Where are most deep sea hydrothermal vents located?
Near rift zones along mid-ocean ridge on the seafloor
The word “hydrothermal”has to do with what processes?
Water that is heated by moving through hot molten rock
Where did Robert Ballard and his team of scientist first discover hydroothermal vents in 1977 
Galapagos rift zone
The fluid that jets out of the hydrothermal vents contains which of the following 
Hot water rich in materials and medals
What is the name of the energy rich chemical compound that is found in high concentrations in hydrothermal vent fluids? 
Hydrogen sulfide 
Which of the following are autotroph’s are producers of the chemo synthetic food web?
Anaerobic bacteria
How do the clams and mussels that live near hydrothermal vents get their food?
Symbiotic bacteria living in their gills manufacture sugars that they use
The poster child of the hydrothermal vent community is a large tube worm
Riftia
Pompeii worm get there food through…
Filtering, suspended bacteria from the water 
What conditions do organisms that live in hydrothermal vent communities go through
Extreme pressure, extreme temperatures, poisonous gases, and heavy metals, perpetual darkness
How are chemosynthetic in photosynthesis similar?
They both use CO2
What is happening at Ralph’s?
New seafloor is being created, Crustal plates are separating, dissolved minerals are flowing from

To form blood contains two blood proteins, a protein that binds hydrogen sulfide, and hemoglobin binds
Oxygen
Which organisms do not live in symbiosis with event bacteria and must actively feed to survive?

Crabs and shrimp
Hydrothermal vent communities collapse, one cut off from the hot, hydrogen, sulfide, rich water. true or false
True
