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.

∙ 14y agoAt the very end of the Precambrian multicelled life evolved. Amonst them jellyfish, invertibrates, sponges and pretty much a prehistoric version of most sealife today.
There is also very suggestive evidence for simple plant life in the form of green algae in the Precambrian.

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
Why is exponential growth unlikely to happen for a very long time?
Because it doesn't take long for the organisms doing the growing to fill the entire Earth.
What will happen to the organisms in this environment over time?
A decreasing number of organisms will be supported by the environment.
What is the process when a scientist works with two organisms Is it called some twinbiofunctioning process?
They usually don't with two as it can confuse the results. If doing an experiment, they do one at a time. Never heard of twinbiofunctioning process.
Dominant organisms in tertiary time period?
The dominant organisms living at the Cretaceous period or time were first primates and flowering plants. This was the time when the extinction of the dinosaurs took place.
What did jellyfish eat during the precambrian time period?
Jellyfish were not even alive during the Precambrian era because only single-celled organisms lived.
What type of organisms dominated life during Precambrian time?
multi-celled organisms
What kind of organism thrived during the Precambrian time?
Prokaryotes. They are single-celled organisms without a nucleus. They were the dominant life form then. They lived in the ocean and the earliest prokaryotes lived without oxygen.
How many living organisms were alive during the precambrian time?
155.92yrs
Did the organisms during the precambrian time have hard body parts?
Nope! They had jelly-like body parts.
What were the life forms in the precambrian era?
The Precambrian Era was the first emergence of complex, multicellular life forms on earth. Jellyfish and segmented worms were discovered to have lived during this time.
When did the ediacaran fauna exist?
The ediacaran fauna lived during Precambrian time and became extinct then, too. Nobody knows for sure why, but trilobites might have caused their disappearance.
Why is it difficult to study Precambrian time?
There is not many remains of the Precambrian time
Is the Earth's surface hot or cool in the Precambrian Time?
It is hot in the Precambrian time
What was the longest segment of the earth's history?
It was the Precambrian time period.
Why do you need to know what organisms lived long time ago?
why do we need to know what organisms live long time ago
What events occurred that allowed single - celled organisms to 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
