Where does the energy from hydrothermal  vents come from?

• active volcanoes heat the water
• magma from the mantle bubbles to the surface
• water is converted to gas that rises through cracks in the ocean floor
• methane leaks from pockets in the crust

What process do the bacteria in vents use to produce energy?

• Photosynthesis
• Chemosynthesis
• Fermentation
• Cellular Respiration

What creature is this?

• Vent Crab
• Vent Shrimp
• Tube Worm
• Ventfish

Where does the energy from hydro-thermal  vents come from?

• Cold Seep
• Steam
• Trench Lakes
• Hot Springs

What color will the smoke be from a vent that has water that leached metals from the mantle and crust?

• Black
• White
• Orage
• Blue

What prevents water from boiling near the vents?

• Extreme Pressure
• Cold Currents
• Methane
• Hydrogen Sulfide

What domain are the bacteria found on these vents from?

• Archea
• Procaryote
• Eukaryote
• Animalia

What two compounds do vents and cold seeps provide for bacteria to turn into energy?

• Oxygen and Hydrogen
• Carbon Dioxide and Methane

Tube worms get energy via

• symbiosis with bacteria
• ingestion of bacteria
• predation
• scavenging

Ventfish get energy via

• symbiosis with bacteria
• ingestion of bacteria
• predation
