Are there more unicellular or multicellular organisms in the world?
There are more unicellular organisms in the world than multicellular organisms. This includes bacteria, archaea, protists, and some types of fungi. Multicellular organisms, like plants and animals, represent a smaller proportion of the total diversity of life on Earth.
What were organisms that lived doing Precambrian time?
Animals that lived during the Precambrian times were single celled animals such as stromatolites,(blue-green algae).The earliest forms of invertebrae animals were also in the Late Precambrian.
Which sequence correctly represents the evolution of life on earth?
Prokaryotes -> Cyanobacteria -> Eukaryotes -> Multicellular organisms Prokaryotes -> Multicellular organisms -> Eukaryotes -> Cyanobacteria Cyanobacteria -> Prokaryotes -> Eukaryotes -> Multicellular organisms The correct sequence is option 1: Prokaryotes -> Cyanobacteria -> Eukaryotes -> Multicellular organisms. These groups represent a general order of the evolution of life on Earth, starting with simple prokaryotic organisms and culminating in more complex multicellular organisms.
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.
What best best describes the first organisms on earth?
The first organisms on Earth were likely single-celled prokaryotes, such as bacteria and archaea. These organisms were simple in structure and adapted to harsh conditions, such as extreme temperatures and lack of oxygen. They played a crucial role in shaping the environment and paving the way for more complex life forms to evolve.
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.
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
Are humans the most abundant organisms on Earth?
No, humans are not the most abundant organisms on Earth. Microorganisms such as bacteria and archaea are the most abundant and diverse organisms on the planet. Humans make up only a small portion of the total biomass on Earth.
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
What does Multi-celled organism mean?
an organism with many cells. another word for multicelled is multicellular. Its more complex. hope this helps!

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 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
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
