What is the source of all food in an ecosystem?
The Sun and in the case of deep sea vents, the heat and chemicals from Earth's interior.
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
What does the theory of plate tectonics suggest about the creation of deep-sea trenches?
They occur where one plate sinks beneath another.
What does the theory of plate tectonics suggest about the creation of deep sea trenches?
They occur where two plates move away from each other.
What are hot springs found deep on the ocean floor called?
thermal vents

How are deep-sea vents formed?
Volcanic eruptions
What is the temperature at a deep sea vent?
Some deep sea vents can be hotter than 300 degrees C.
What do geysers and deep-sea vents that from chimneys have in common?

Water released from deep-sea vents has been heated by?
hot rocks deep in the crust.
Chemosynthetic communities in the ocean can be found?
surrounding deep-sea hydrothermal vents
Why are hydrothermal vents helpful to the deep sea ecology?
Hydrothermal vents allow underground heat sources to warm the ocean bottom which is necessary to support deep see ecology.
Where would you expect to find chemosynthetic organisms?
such organisms would be bacteria, fungi, protozoa, algae and other microorganisms mostly you would only need to find a rock and have a powerful microscope
Where do some scientist think bacteria originated?
near deep-sea hydrothermal vents
Where do some scientists think these bacteria originated?
near deep-sea hydrothermal vents
