how long has archaebacteria been on earth? how long has archaebacteria been on earth?
Archaebacteria are some of the oldest organisms living on Earth. They are considered simple because of their external body structure.
Archaebacteria have contributed to life on Earth by playing essential roles in various ecosystems, such as extreme environments like hot springs and deep-sea vents. They have also been crucial in the evolution of early life forms and the development of metabolic pathways that influenced the diversity of life we see today. Additionally, some archaebacteria are involved in processes like nitrogen fixation and methane production, which are important for nutrient cycling in the environment.
According to the books archaebacteria was thought to be the first living being existing when the earth was cooling down initially. they were the methanogenic, thermophillic and most chiefly were anaerobic. Would these characteristics have been helped the earth to create its present environment?
they have been on the earth for along time
They have been on earth since 190 million years ago.
long time
for as long as it has had continents
A very long time.
i have been on this earth for 8 years
Well it depends on what you mean. The distance for how long it takes, or the time as in how long since Earth was made. Earth as you know has been here a long long time. Stars light has been shinning towards Earth eversince it was made. To see how long it takes for a stars light to reach Earth depends on how distant and huge the star is.
If you've ever been to Yellowstone national park in Utah, you've seen Archaebacteria, mostly in the boiling water and mud-pots. They enjoy (by which I mean survive) extremely hot, sulfuric, moist areas.
Archaebacteria are the oldest organisms living on earth. They are unicellular prokaryotes and belong to the kingdom Archaea. They can be found in very harsh conditions such as volcanic vents or the tundra.
