A lot of organisms that thrive in the deepest parts of the ocean rely heavily on chemosynthesis.
Chemosynthesis is most commonly seen near thermal vents and involves the biological conversion of 1+ carbon molecules (methane/CO2) and nutrients into organic matter. This is made possible through the oxidation of inorganic molecules such as H2 or Hydrogen Sulfide; these are used as a source of energy, rather than radiation from the sun.
What else can I help you with?
Propose a question that a scientist might ask about the variety of organisms found around deep sea vents?
lol your scerwed i have the same question in my pearson succes thing
Why do organisms living in the pelagic zone below 200 meters depend on organisms living above that depth to supply their energy?
Plant photosynthesis is the primary source of nutrients in every ecosystem. Deep in the ocean, where little or no sunlight is present, photosynthesis is impossible. Thus, organisms in deep water ecosystems depend on detritus (discarded waste) and other organic matter that drifts down from (and is generated) nearer to the surface, or on species that migrate back and forth.
Some organisms use chemosynthesis to survive. Where do they get energy for this process?
From ocean chemicals
Where would you expect to find chemosynthetic organisms?
Chemosynthetic organisms are typically found in environments where sunlight is limited or absent, such as deep-sea hydrothermal vents, cold seeps, and caves. These organisms are capable of using chemicals as an energy source to produce food through chemosynthesis, rather than relying on photosynthesis.
What organisms depend on water?
Tides normally have detrimental effects on living things. Most of the living things are displaced by the heavy tides and there is so much waste that is deposited on the shores which ends up hurting the environment.
For carbon fixation what process do deep-sea organisms depend on?
Deep-sea organisms depend on chemoautotrophic bacteria, which use chemical energy from sources like sulfur compounds to fix carbon dioxide and synthesize organic molecules through a process called chemosynthesis. This allows deep-sea organisms to survive in environments where sunlight cannot penetrate for photosynthesis.
What process produces deep-sea trenches?
A process known as subduction creates deep sea trenches.
What group of organisms does not depend on sunlight?
Deep sea organisms living near hydrothermal vents do not rely on sunlight for energy. Instead, they derive energy from chemicals present in the hydrothermal fluids. These organisms form unique ecosystems that are independent of photosynthesis.
What produces deep sea trenches?
A process known as subduction creates deep sea trenches.
What are deep-sea vent organisms evidence of?
Deep-sea vent organisms are evidence of chemosynthesis, a process where organisms derive energy from chemicals in their environment instead of sunlight. They are also evidence of the adaptability of life to extreme environments, thriving in high-pressure, high-temperature, and high-toxicity conditions.
The ocean floor is hard to get to Deep-sea organisms have been difficult to study. How do I combine these two sentences to make a correct one sentence?
Deep-sea organisms have been difficult to study because the ocean floor is hard to get to.
What happens to the deep sea organisms if they are brought to the surface?
they usually die
How do organisms at deep sea vents survive without oxygen?
These organisms do not need oxygen. They are called anaerobes.
What are deep sea producers?
Deep sea producers are the organisms that live so far down in the ocean, that they have to make their own food in order to live.
What organisms can you list that don't depend on photosynthetic organisms for their food either directly or indirectly?
Organisms that don't depend on photosynthetic organisms for their food include certain deep-sea hydrothermal vent organisms that rely on chemosynthesis, carnivorous animals that feed on other animals, and decomposers such as fungi and bacteria that break down organic matter.
What process produceces deep sea trenches?
Subduction.
What organisms are an exception to the rule that all life energy comes from the sun?
Organisms that live in deep-sea hydrothermal vents are an exception as they derive energy from chemical reactions in the absence of sunlight. These organisms, like certain types of bacteria and archaea, use a process called chemosynthesis to convert minerals and chemicals in the vent water into energy for survival.
