What events occured 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
Why do tropical rain forests have more biological diversity than other places on earth?
Tropical rain forests have more biological diversity than other places on earth because the conditions allow more organisms to live there. The rain forest gives many organisms suitable homes.
How would the increasing number of photosynthesizing organisms on earth have affected both earth and its other organisms?
As the first photosynthetic organisms increased in number, the concentration of oxygen in Earth's atmosphere began to increase. Organisms that could respire aerobically would have evolved and thrived. The sun's rays would have converted much of the oxygen into ozone molecules that would then have formed a layer that contained more ozone than the rest of the atmosphere.
Are there more unicellular or multicellular organisms in the world?
There are more unicellular organisms in the world. eg:- bacteria
Which group of organisms can show significant trait changes in the shortest period of time?
In terms of evolution, bacteria are some of the fastest evolving organisms on Earth. This is because they reproduce so quickly (sometimes in 20 minutes) and that means that more organisms are made and more variation exists. This allows for more traits to be selected by natural selection, resulting in the fastest trait changes within a population.
Multicellular organisms are more advanced than unicellular organisms?
No, the majority of organisms on Earth are unicellular. But we multicellular organisms are the more interesting kind. Multicellular organisms rule!
What are multicellular eukaryotic autotrophs?
A heterotroph is an organism that requires other organism to survive. Multicellular organisms have more than one cell. So being multicellular and heterotroph means that the organism is multicelled and depends on other organisms to survive.
Are humans the most abundant organisms on Earth?
No. The most abundant organisms are insects. There's more of them than there are people. The most abundant organisms are bacterias.
What type of organisms dominated the earth for more than the first half of the history of life on earth?
Dinosaurs were the one who dominated the earth
Which area is affected by decreased amounts of ozone?
area 4: more UV light reaches the earth causing damage to organisms <3
If you keep littering what will happen to the earth?
the earth will contaminate more than it is now that would provoke the extinction of lots of organisms
Are all organisms made of more than one cell?
The branch of science that deals with microorganisms
Why do tropical rain forests have more biological diversity than other on earth?
Tropical rain forests have more biological diversity than other places on earth because the conditions allow more organisms to live there. The rain forest gives many organisms suitable homes.
What are are multicellular organism?
Unicellular- organisms include bacteria, the most numerous organisms on Earth. Multicellular- organisms are composed of many sells and they lie
What does Multi-celled organism mean?
an organism with many cells. another word for multicelled is multicellular. Its more complex. hope this helps!
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
When did the earliest organisims appear on Earth?
Nobody really knows when the earliest organisms were on Earth. It was definitely more than a million years ago.
