What else can I help you with?
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.
What two major processes are involved in the oxygen cycle?
Photosynthesis, which involves plants and other organisms using sunlight to convert carbon dioxide into oxygen, and respiration, where organisms use oxygen and release carbon dioxide as a byproduct.
Organisms that are poisoned by oxygen and must live in very low oxygen regions are called?
Obligate anaerobes are poisoned by O2 and use fermentation or anaerobic respiration
How do freshwater marine organisms get oxygen?
Freshwater marine organisms obtain oxygen through diffusion across their body surface or through specialized respiratory structures like gills. They extract dissolved oxygen from the water around them to support their metabolic processes. Some organisms, like fish, have a more efficient respiratory system to extract oxygen from water.
Why must aerobic organisms inhale oxygen and exhale CO2?
Aerobic organisms require oxygen for cellular respiration to produce energy in the form of ATP. During this process, they inhale oxygen and exhale carbon dioxide as a byproduct. Carbon dioxide is a waste product that needs to be removed from the body to maintain proper pH levels.
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.
What do you call to the organisms which do not use oxygen?
plants
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 does not use oxygen in it metabolism?
Anaerobic organisms do not use oxygen in their metabolism. These organisms can generate energy through fermentation or anaerobic respiration, which does not require oxygen. Examples include certain types of bacteria and yeast.
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.
What is the name of an organism that requires oxygen?
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
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.
What are organisms that must have oxygen to survive?
Obligate aerobes are organisms that require oxygen to survive, as they use it for their cellular respiration process. These organisms cannot grow or survive in environments with low oxygen levels. Examples include humans, most animals, and many bacteria.
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.
Some organisms in the ocean use this greenhouse gas for photosynthesis and shell?
oxygen
How do organisms get energy in the absence of oxygen?
Organisms can obtain energy in the absence of oxygen through a process called anaerobic respiration. This involves breaking down molecules like glucose without using oxygen. Different organisms may use different pathways such as fermentation to produce energy without oxygen.
What are the products of photosynthesis used by other organisms?
The products of photosynthesis, such as glucose and oxygen, are used by other organisms as a source of energy. Glucose is a key source of energy for many organisms, including plants, animals, and bacteria. Oxygen is used by animals for respiration to produce energy.
