Which organism is killed by atmospheric o2?
Anaerobic bacteria are organisms that are killed by atmospheric oxygen. They thrive in environments without oxygen, and exposure to oxygen can be lethal for them.
What produces most of the earths atmospheric oxygen?
The majority of Earth's atmospheric oxygen is produced by marine phytoplankton through the process of photosynthesis. These microscopic organisms play a crucial role in the oxygen cycle by converting carbon dioxide and sunlight into oxygen.
What organism is killed by atmospheric oxygen?
Obligate anaerobes, such as certain bacteria, are organisms that cannot survive in the presence of atmospheric oxygen because it is toxic to them. Exposure to oxygen can damage their cellular structures and metabolic processes, leading to their death.
Why is oxygen important to the ocean?
Oxygen is important to the ocean because it is needed by marine organisms for respiration. It supports the survival of fish, plants, and other marine life. Dissolved oxygen levels in the ocean are crucial for maintaining healthy ecosystems.
What organism produce about half of the oxygen?
Marine phytoplankton, such as diatoms and cyanobacteria, are responsible for producing about half of the oxygen in the Earth's atmosphere through the process of photosynthesis. These tiny organisms play a vital role in the global oxygen cycle and support the health of marine ecosystems.
What are two sources of oxygen in seawater at the surface?
Two sources of oxygen in seawater at the surface include atmospheric exchange, where oxygen from the air dissolves into the water, and photosynthesis by marine plants and phytoplankton, which produce oxygen as a byproduct.
Which atmospheric gases is probably the most important for human survival?
Oxygen is the most important atmospheric gas for human survival. It is essential for cellular respiration, providing the energy needed for our bodies to function properly. Without oxygen, we would not be able to survive.
Why are nitrogen oxygen and carbon dioxide important to marine organisms?
Nitrogen is important for marine organisms because it is a key component of amino acids and proteins. Oxygen is vital for respiration in marine organisms, enabling them to extract energy from food. Carbon dioxide is involved in photosynthesis, where marine organisms like phytoplankton use it to produce energy and oxygen.
Why is every organism in a community important?
They provide oxygen, shelter and food for the organisms
What important gas to plants make?
Most plants release some oxygen from atmospheric carbon dioxide.
What was primarily responsible for the development of life outside of the oceans?
"An increase in atmospheric oxygen"An increase in atmospheric oxygen
Where does the bulk of atmospheric oxygen originate from?
The bulk of atmospheric oxygen originates from photosynthesis by plants and phytoplankton in the oceans.
