Life is suggested to have started in an aquatic ecosystem - the ocean.
Explanation:
For decades, life has been suggested to have started in an aquatic environment due to evidence of ancient fossils and chemical studies.
Recently, scientists have been able to narrow these suggestions to state that life originated in a deep sea hydrothermal vent. This hypothesis arised due to the presence of chemicals that are thought to have produced the chemical reactions that are necessary for the evolution of life.
The first living forms on Earth were single-celled micro-organisms called stromatolites - <em>rock-like structures formed by cyanobacteria</em> - that appeared around four billion years ago. Interestingly, we are still able to find these ancient creatures but only in specific regions of the world such as Cuatro Cienegas, Coahuila in Mexico.
Hi,
Autotrophs are biotic factors.
I’m not sure of this but I think this is like a science question so check in your book it should talk about the jack hammer if not , dm !
