How plentiful are unicellular and multicellular organisms?
Amount of Unicellular and Multicellular OrganismsMore than 1 and 1|2 (one half) million kinds of organisms have been identified. That number is small compared to the estimated number of unicellular organisms that exist and have not been identified. Scientists estimate that there are more than 1 billion kinds of unicellular organisms!
Does Fabric have cells?
No. Cells only exist in living organisms. materials are made out of billion and billion of atoms and molecules.
Which event contributed most directly to the evidence of aerobic organism?
The development of photosynthesis in primitive organisms, specifically cyanobacteria, contributed most directly to the evidence of aerobic organisms. Photosynthesis evolved around 3 billion years ago, producing oxygen as a byproduct. This oxygen accumulation in the atmosphere eventually allowed for the development of aerobic organisms, which rely on oxygen for their metabolism.
What era did the atmosphere change due to living organisms?
The presence of organisms played a crucial role in shaping Earth's atmosphere. An organism must interact with the environment, taking in and producing material to sustain life. Early organisms took in carbon dioxide and produced sea sediment.
How old is the atmosphere?
The Earth is about 4.5 billion years old and has had an atmosphere since it formed, but about 3.8-4.1 billion years ago there was believed to be the Late Heavy Bombardment, where a planetesimal roughly the size of Mars hit the Earth, breaking off a large chunk that formed into the Moon. This impact would have obliterated the atmosphere, but it has reformed naturally since then. So, the answer to your question is approximately 4 billion years old.
How did oxygen get in your atmosphere?
Oxygen was released from Precambrian rocks. cynobacteria were the first organisms to produce oxygen 2.5-3 billion years ago
What changes were necessary in earth's atmosphere to allow complex organisms to evolove?
During the few billion years following the appearance of cyanobacteria, oxygen became a major gas in Earth's atmosphere. The ozone layer in the stratosphere also began to develop, shielding Earth from ultraviolet rays. These major changes in the air allowed species of single-celled organisms to evolve into more complex organisms.
How many billion of years old is the universe according to scientists?
14 billion

Why did the amount of oxygen's in earths atmosphere increase dramatically?
The amount of oxygen in the atmosphere increased because the number of photosynthetic organisms, which release oxygen, on the earth dramatically increased. This lead to the Great Oxygenation Event, or the Oxygen Crisis, 2.4 billion years ago - when this free O2 entered the Earth's atmosphere.
What element transformed carbon dioxide atmosphere a billion years ago to what you breathe?
Oxygen is the element that transformed Carbon Dioxide atmosphere a billion years ago to what you breathe.
How has the atmosphere changed over the last 4.5 billion years?
Due to photosynthesising, single celled organisms, the atmosphere now has much more oxygen in it. this is possibly the most important change as with out we would exist. The atmosphere originally had much more carbon-dioxide and made the planet so hot humans would not be able to survive.
How old do scientists think that earth is?
4.6 billion years
What bacteria are thought to be responsible for establishing Earth's oxygen-rich atmosphere?
Cyanobacteria are believed to be responsible for establishing Earth's oxygen-rich atmosphere. Nearly 2.3 billion years ago, these microbes, which lived in the seas, were the first organisms to produce oxygen, leading to the transformation of the Earth's environment.
Was the earth's atmosphere always the same?
No, actually it took a period of about 2.5 billion years for the atmosphere to be were it is today.
What will be the population in 2050?
About 9.2 billion. Imagine all of the waster pollution going into out atmosphere by then!
Does Fabric have cells?
No. Cells only exist in living organisms. materials are made out of billion and billion of atoms and molecules.
