What else can I help you with?
What process would give an organism oxygen?
The process that gives an organism oxygen is photosynthesis. During photosynthesis, plants, algae, and some bacteria use sunlight to convert carbon dioxide and water into glucose and oxygen. This oxygen is released into the atmosphere and is crucial for the survival of many organisms.
How does oxygen get into a unicellular organism?
Oxygen can diffuse into a unicellular organism through its cell membrane. The organism utilizes this oxygen for cellular respiration to produce energy.
What prokaryotic cells that were the first to add significant quantities of oxygen to Earth's atmosphere are classified as?
Prokaryotic cells that were the first to add significant quantities of oxygen to Earth's atmosphere are classified as cyanobacteria. Cyanobacteria are photosynthetic bacteria that played a crucial role in the Great Oxidation Event, releasing oxygen as a byproduct of photosynthesis. Their activity contributed to the oxygenation of Earth's atmosphere and paved the way for the evolution of aerobic life forms.
What do you call an organism requiring oxygen?
An organism that requires oxygen for its survival and metabolism is called an aerobic organism. These organisms rely on oxygen to produce energy through aerobic respiration.
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
What organism added oxygen to your atmosphere and why?
Plants, trees, and grass put oxygen into the air.
How do organism add carbon to the atmosphere?
When a organism dies and decays it emits carbon dioxide.
What organism contributed the most to the shift between an oxygen-free atmosphere to an oxygenated-atmosphere?
The 'photosynthtics'
What is the process when organisms add oxygen to the atmosphere called?
photosynthesis
When plants make their own food they add what gas to the atmosphere?
Plants add oxygen to the atmosphere during photosynthesis or food making.
Does photosynthesis add oxygen to the atmosphere?
Yes, photosynthasis does add oxygen to the atmosphere becaause the organisms (plants) developed the ability to photosynthasise. By taking in carbon dioxide and releasing oxygen.
Which organism release oxygen into the atmosphere?
Plants, particularly through the process of photosynthesis, release oxygen into the atmosphere as a byproduct. This oxygen is essential for the survival of many organisms, including humans, who rely on it for respiration.
What did cyanobacteria add to the atmosphere?
Cyanobacteria added oxygen to the atmosphere through the process of photosynthesis, fundamentally changing the composition of Earth's atmosphere and enabling the evolution of aerobic organisms.
What organism is given credit for helping change the gases in your atmosphere to oxygen?
Probably ancient cyanobacteria.
What element upon which most modern organism depend was missing from earth's early atmosphere?
Oxygen
When plants make their own food what gas do they add to the atmosphere?
Most importantly, carbon dioxide is absorbed by plants in order to photosynthesise. The oxygen is absorbed when plants respire. The atmosphere is the source of rain for their water. Physical aspects of the atmosphere, such as strong winds, can damage plants.
What was the first organism to add oxygen to the earth?
Cyanobacteria, which are sometimes incorrectly called blue-green algae, were the first organisms to add oxygen to early Earth. Blue-green algae are eukaryotes while cyanobacteria are the much earlier prokaryotes.
