Are onecelled organisms with shells made of silica?
Diatoms.
How do colonies of cyanobacteria harm aquatic organisma?
Some cyanobacteria fix nitrogen from atmosphere.
The type of organisms that create stromatolites?
cyanobacteria
The oxygen had originally been excreted as metabolic waste from what organisms?
cyanobacteria
Organisms that makes food by photosynthesis?
Algae, plants, and cyanobacteria.
What organisms contributed the most to the shift between an oxygen free atmosphere to an oxygenated atmosphere?
cyanobacteria

Which of these statements is true about the oxygen revolution?
Cyanobacteria were the first organisms to produce oxygen in water, which then escaped into the atmosphere.
How did cyanobacteria prepare the way for the origin of aerobic respiration?
The evolution of aerobic organisms depended on a metabolic product of cyanobacteria because they used them as a energy source and supply to maintain their health.
What unique ability was originated with cyanobacteria?
Cyanobacteria were the first organisms to perform oxygenic photosynthesis, a process that uses sunlight to produce oxygen as a byproduct. This ability ultimately led to the increase of oxygen in the Earth's atmosphere, paving the way for the development of aerobic life forms.
What are the structures found in the blood called erythrocytes?
many onecelled colonial and simple multicelluar organisms rely on which of the following transport mechanisms
What was the first organism to add oxygen to the earth?
Cyanobacteria, which are sometimes incorrectly called blue-green algae, were the first organisms to add oxygen to early Earth. Blue-green algae are eukaryotes while cyanobacteria are the much earlier prokaryotes.
The type of organisms that create stromatolites?
cyanobacteria
Describe the significance of cyanobacteria in the formation of earth's atmosphere?
cyanobacteria also called blue-green algae is thought to be one of the first ever photosynthetic organism...prior to the evolution of photosynthetic organisms theoxygen percentage of the atmosphere was 0% and as we all know without oxygen (O2), ozone(O3) cannot form, and without ozone there can be no atmosphere. Photosynthetic organisms allowed for the formation of oxygen and brought oxygen levels to the percentage it is today (20% a significant increase from 0%) as a result ozone was able to form and ultimately the atmosphere emerged.
What are simplest organisms?
Prokaryotes, like bacteria and cyanobacteria.
