What was the first living creature on earth?
This question depends on what you mean by, "Living creature." The first single celled organisms predated bacterium and their DNA most likely contained only the most basic design. These creatures later helped form an atmosphere of CO2 and O2, paving the way for larger Oxygen-reliant organisms.
What gas must animals breathe to live?
Oxygen. of course!! All living beings need oxygen to live on earth.
How does the earth keep us alive?
The Earth keeps us safe in many various ways, but the most common is that it provides us with shelter, food, water, and most importantly oxygen. If there was no Earth, then there would be no humanity. Humans wouldn't be alive today.
Why do plants produce more carbon dioxide than oxygen during the night t?
Oxygen is produced by photosynthesis, which can only occur when there is light present. Carbon dioxide is produced by respiration, which occurs all the time, including night. or Respiration can happen without sunlight, but photosynthesis cannot.
From where does most of the oxygen in the atmosphere come?
Most but perhaps not all began when tiny organisms known as cyanobacteria, or blue-green algae (in the seas and oceans) began conducting photosynthesis: using sunlight, water and carbon dioxide to produce carbohydrates and oxygen.In fact, all the plants on Earth incorporate symbiotic cyanobacteria (known as chloroplasts) to do their photosynthesis for them today.
Was oxygen on Earth before or after life on Earth?
Elemental oxygen did not appear on Earth until some time after life did. In fact, the oxygen was produced by life carrying out photosynthesis. The first organisms on Earth were anaerobic, meaning their life processes did not involve oxygen. To most organisms like this, oxygen was highly toxic.
Which protists group produced most of the oxygen on earth?
All of them exhale carbon dioxide.
Most of the worlds oxygen is produced by?
Most of the worlds oxygen is produced by Trees.
Does air come from the sun?
No. Earth's atmosphere most likely originate from volcanic atmosphere. The oxygen is produced by plants.
Which gas was first produced on earth by cyanobacteria?
Cyanobacteria also called as blue green algae. They are the photosynthetic prokaryotes. They are found in both marine and freshwater. They are probably the most numerous taxon to have ever existed on earth and the first organism know to have produced oxygen.
How much of the earth's oxgyen is produced by the equatorial forest?
About 2% of the Earth's oxygen it produces.
Who produced 80 percent to 90 percent of earth oxygen?
phytoplankton :)
How did earth get oxygen 4 billion years ago?
From primitive bacteria that produced oxygen as a waste product.
Most of the oxygen you breath is produced by?
plants
What did precambrian cyanobacteria do?
Cyanobacteria produced oxygen through photosynthesis which led to the oxidizing of earth.
Oxygen is the most abundant element by volume in Earth's?
Oxygen is the most abundant element in Earth's crust.
How much oxygen is produced by a tree?
a lot of oxygen! that's where most of it comes from!
