What were blue green algae responsible for making?
Blue-green algae, also known as cyanobacteria, were responsible for producing a significant amount of the oxygen in Earth's early atmosphere through photosynthesis. They were also one of the first organisms to produce oxygen on Earth, leading to the oxygenation of the atmosphere.
How are multicellular aglae important at a global level?
Multicellular algae is crucial to the atmosphere, as it actually produces the greatest percentage of oxygen in our atmosphere, compared to other photosynthetic organisms.
What makes it safe to live on Mars?
Breathable atmosphere, lots of fur coats, algae, water, and impenetrable shelter.
How are the nitrogen cycle and the water cycle alike?
explain how nitrogen cycles through the land and ocean ecosystems
Where do algae get the carbon dioxide?
Algae obtain carbon dioxide primarily from the surrounding water, where it is present in dissolved form. During photosynthesis, algae absorb CO2 from the water and use it, along with sunlight and nutrients, to produce organic matter and oxygen. Additionally, carbon dioxide can also enter the water from the atmosphere, where it diffuses into aquatic environments. This process is essential for the growth and energy needs of algae.
What added oxygen to earth atmosphere as they made food there?
The biggest contributer was and is algae.
What did Algae lower in the atmosphere?
Great blooms of oceanic algae, or phytoplankton, take carbon out of the atmosphere during photosynthesis. It is then taken deep into ocean with them when they die. Scientists say that this helped cool the earth during the ice ages by removing carbon dioxide from the atmosphere and storing it at the ocean floor, where it cannot be recycled back into the atmosphere.
Plants and other photosynthetic organisms such as algae take in from the atmosphere and combine it with water and energy from the sun to form sugar.?
Plants and other photosynthetic organisms such as algae take in ________ from the atmosphere and combine it with water and energy from the sun to form sugar.

Blue-green algae, also known as cyanobacteria, were responsible for producing a significant amount of the oxygen in Earth's early atmosphere through photosynthesis. They were also one of the first organisms to produce oxygen on Earth, leading to the oxygenation of the atmosphere.
What way did algae change the atmosphere earth?
Algae played a critical role in changing the atmosphere of Earth by producing oxygen as a byproduct of photosynthesis, which gradually increased the oxygen levels in the atmosphere. This oxygenation helped create conditions that supported the evolution of more complex life forms over time.
What gas is removed from the atmosphere by plants and algae?
Carbon dioxide (CO2) is removed from the atmosphere by plants and algae through the process of photosynthesis. They use CO2 during photosynthesis to produce oxygen (O2) and carbohydrates.
Algae help return nitrogen to the soil?
Yes, certain types of algae can fix atmospheric nitrogen into a form that is usable by plants, helping to replenish nitrogen levels in the soil. This process, known as nitrogen fixation, plays a vital role in ecosystem productivity and nutrient cycling.
What would happen to earth's atmosphere if algae died off?
Oxygen levels would increasethey wouldnt increase they would decrease because 80% of oxgyen is from algae
Starting billions of years ago algae lowered the?
...lowered the level of CO2 in the atmosphere and released O2
How are multicellular aglae important at a global level?
Multicellular algae is crucial to the atmosphere, as it actually produces the greatest percentage of oxygen in our atmosphere, compared to other photosynthetic organisms.
What is a sentence for replenish?
replenish is to fill up or stock
The oxygen content in the atmosphere of the early Earth is thought to have increased significantly once which of these developed?
green plants / algae
