Are there more single-celled or multi-celled organisms on earth?
multi-celled organisms have more than 1 cell.But a singe-celled organism does not.
What important role do unicellular organisms play in sustaining life on Earth?
Single celled lifeforms constitute most of the life on Earth. They are the majority of the producers in Earth's ecological system. They are major contributors to the processes that replenish our atmosphere, and form the basis of the marine food chain. On a smaller scale, single celled organisms perform equally important roles: they are a major part of the digestive system of most advanced animals. In humans, they are present in our intestines to aid in the breakdown of foodstuffs. Without them, we would not survive. Without single celled organisms, no life would be possible on Earth.
How many years did single celled organisms dominated the earth?
4 billion
What events occured that allowed single celled organisms to evolve into more complex organisms at the end of the precambrian time?
the ozone layer began to develop shielding earth from ultraviolet rays, this was hypothesized that these changes allowed species of single celled organisms to evolve into more complexed organisms
What were organisms that lived doing Precambrian time?
Animals that lived during the Precambrian times were single celled animals such as stromatolites,(blue-green algae).The earliest forms of invertebrae animals were also in the Late Precambrian.
