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.
As far as we know for the majority of the Precambrian super-eon the only life on earth was bacteria.At 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.

Kind of like Gurveer
do not kill any kind of organism.
During the Precambrian Era, life forms were predominantly single-celled organisms such as bacteria and algae. These organisms were simple and lacked the complex structures seen in later eras. It was a time of significant evolution and diversification of life on Earth.
