The earliest known group of living organisms on earth was?
Prokaryots
Earliest known group of living organisms?
The earliest known group of living organisms are believed to be prokaryotes, such as bacteria and archaea. They are single-celled organisms that lack a distinct nucleus and other membrane-bound organelles. Prokaryotes are thought to have appeared on Earth billions of years ago.
What were the first know living organisms on earth and when did they appear?
The first known living organisms on Earth were likely single-celled prokaryotes, such as bacteria and archaea, which appeared around 3.5 billion years ago. These simple organisms were among the earliest forms of life to emerge on our planet.
What is the oldest earliest known group living organism on earth?
The oldest known group of living organisms on Earth is believed to be cyanobacteria, which are photosynthetic bacteria that have existed for about 3.5 billion years. Fossil evidence, such as stromatolites, shows that these microorganisms played a crucial role in shaping early Earth's atmosphere by producing oxygen through photosynthesis. Their long history makes them key players in the evolution of life, contributing to the development of more complex organisms.
What is the earliest group or living organisms on earth?
The archeobacteria. Very primitive bacteria that live in extreme conditions - hot springs, thermal vents on the ocean floor, extremely salty saline pools and even in Antarctic ice
What is the largest variety of living organisms on earth is called?
A kingdom is the largest group into which living things can be classified.
What is the group of organisms of one kind that live in one location?
P-o-p-u-l-a-t-i-o-n
What group of organisms alive today are most similar to the first cells on earth?
Archaea are considered to be the group of organisms most similar to the first cells on Earth. They are single-celled microorganisms that have simple cell structures and thrive in extreme environments, similar to the conditions present on early Earth.
What is the most likely consequence if a group of living organisms is unable to adapt to changing conditions within the Earth system?
If a living system, or group of organisms, cannot adjust to an envirormental change, it will be out-competed by groups that can. The organism will have to find a new way to survive or it will die out, survival of the fittest.
Why do they classify species?
The structures of living organisms is very complex and very different from one organism to another; species are classified to group similar kind of living organisms through knowing about their metabolic and catabolic activitiesThis makes it less complex to study the developmenthistory and science of evaluation of living organisms on earth.
What is the smallest group into which scientists classify living things?
The smallest group into which scientists classify living things is a species. A species is a group of organisms that can interbreed and produce fertile offspring.
What is the most abundent group of organisms on earth?
bacteria
