The ultimate source of energy for all organisms except those living deep in the ocean near a thermal vent is the?
phytoplankton
What is the ultimate source of energy for almost all organisms except those living deep in the ocean near thermal vent?
phytoplankton
What do vent tubeworms and chemosynthetic bacteria get from there close relationship?
They get food
What is the cylindrical opening that connects a source of molten rock with the surface of the earth?
Volcanic Vent.
How are fumaroles different from hot springs?
A fumarole is a vent on or near a volcano that emits gas. A hot spring is a pool of water heated by an underground source.
The ultimate source of energy for all organisms except those living deep in the ocean near a thermal vent is the?
phytoplankton

What is the ultimate source of energy for almost all organisms except those living deep in the ocean near thermal vent?
phytoplankton
What is the ultimate source of energy for almost all organism except those living deep in the ocean near a thermal vent?
The sun.
What role do chemosynthetic bacteria play in deep-sea volcanic-vent ecosystems?
It serves as a food source to organisms in the deep water
Is a vent a source convection conduction or radiation?
conduction
What is at the top of the food chain near a hypothermal vent?
There is no such thing as a "hypothermal" vent.
Why is the tube worm riftia?
what is the estimated life of a hydrothermal vent community
What is a energy source for hydrothermal vent?
The heat from deep in the earth's mantle.
Producers in a hydrothermal vent community are?
There are none. No sunlight penetrates that deep, so there is no sunlight for photosynthesis. Instead, bacteria use chemosynthesis. They take the chemicals in the water shooting out of the vents, and make it into food.
What is the energy source in vent ecosystems deep in the oceans?
Heat from Earth's interior.
How is energy transsferred in a thermal vent community?
Some archaebacteria, such as thermophiles, live by hydrothermal vents. They are chemoautotrophs, which means that they produce their own food using energy from the chemicals in the vents instead of using energy from the sun. The energy starts in the vent, then goes to the archaebacteria, then to the organisms that eat those archaebacteria, and so on.
