Oxygen is essential for cellular respiration in organisms, where it is used to produce energy. Without oxygen, most living organisms would not be able to survive. However, prolonged exposure to high levels of oxygen can also be toxic to certain organisms, causing damage to cells and tissues.
What else can I help you with?
What are organisms that release oxygen?
Organisms that release oxygen as a byproduct of photosynthesis include plants, algae, and cyanobacteria. These organisms use sunlight to convert carbon dioxide and water into oxygen and glucose, releasing oxygen into the atmosphere as a result.
What are 2 ways organisms obtain oxygen?
Organisms obtain oxygen through respiration, where they take in oxygen from their environment and release carbon dioxide as a waste product. Aquatic organisms such as fish can also extract oxygen from the water through their gills.
Are all organisms on earth will die without a constant supply of oxygen true or false?
False. While most organisms require oxygen for survival, there are some anaerobic organisms that can live in environments without oxygen. These organisms have adapted to use other molecules for energy production.
How does oxygen living organisms?
Oxygen is essential for most living organisms because it is used in the process of cellular respiration to produce energy. Organisms use oxygen to break down food molecules and generate ATP, the energy currency of cells. Without oxygen, many organisms would not be able to carry out this vital process and would not survive.
What are organisms which need oxygen to survive?
Organisms that need oxygen to survive are known as obligate aerobes. These organisms require oxygen for their metabolism and cellular respiration to produce energy. Examples include humans, most animals, and many types of bacteria.
What effect did photosynthetic cyanobacteria have on earth's environment?
Photosynthetic cyanobacteria were the first organisms to produce oxygen. The effect of their oxygen production was that the earth became an environment which was suitable for life.
How might the photosynthetic organisms counter the greenhouse effect?
Photosynthetic organisms counter the greenhouse effect. This is because plants use carbon dioxide and turns it into oxygen instead. Carbon dioxide is causing the greenhouse effect.
Did organisms that require oxygen exist before photosynthetic organisms?
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
Organisms that use oxygen?
Aerobic organisms use oxygen.
The by-product of the metabolism of cyanobacteria that had the most effect on the further evolution of life is?
Oxygen. Cyanobacteria were one of the earliest organisms to produce oxygen as a by-product of photosynthesis. This oxygenation of Earth's atmosphere had a profound impact on the further evolution of life, leading to the diversification of aerobic organisms.
What are the effects of living organisms on the earths surface?
Biggest effect is oxygen. Minor effects is a temperature regulation by modulation of CO2.
What is the alteration in aquatic bodies which has a negative effect on apnatic organisms?
An increase in water temperature can lead to decreased oxygen levels in aquatic bodies, negatively impacting apnatic organisms like fish. This decrease in oxygen availability can lead to respiratory stress, reduced metabolism, and overall lower survival rates for these organisms.
What are organisms that release oxygen?
Organisms that release oxygen as a byproduct of photosynthesis include plants, algae, and cyanobacteria. These organisms use sunlight to convert carbon dioxide and water into oxygen and glucose, releasing oxygen into the atmosphere as a result.
How do organisms at deep sea vents survive without oxygen?
These organisms do not need oxygen. They are called anaerobes.
What do organisms do with the oxygen they absorb from the air?
Organisms use the oxygen they absorb from the air for their cells. The cells need this oxygen in order to carry out their functions.
Organisms get their oxygen from?
respiration
How do organisms get their oxygen from?
respiration.
