How will the change in sea levels affect organism on Earth?
The change in sea levels will prevent many organisms from migrating. Marine organisms will be the most likely to adapt.
When did the biosphere begin to evolve?
The biosphere is defined as the living organisms on earth. As such, it began to evolve when the first organisms appeared. Currently, this is believed to have happened about 3.5 billion years ago.
How did earth's organisms change during the first period of Paleozoic era?
increased oxygen in the atmosphere caused the extinction o many single-celled organisms.
What events occurred 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
What are the most numerous organisms on earth?
Bacteria, the most numerous organisms on Earth , are unicellular organisms - just had this question on a homework

What is the term for the biological process by which the kinds of organisms on earth change over time?
Evolution
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

How will change in sea levels affect organisms on earth?
Rises in sea level will flood coastal cities and croplands, causing distress to many organisms, especially humans.
How does earth geological features affect the ability of organisms to live in different places?
Earth geological features affect the ability of organisms to live in different places because the temperatures change. Since animals and other organisms have different requirements to live, they have to live in different places.
