Where does 80 percent of oxygen comes from?
Around 80 percent of oxygen on Earth is produced by phytoplankton in the oceans. These microscopic organisms undergo photosynthesis, absorbing carbon dioxide and releasing oxygen into the atmosphere. Forests and other terrestrial plants also contribute significantly to oxygen production.
What is the mass percent of oxygen?
The mass percent of oxygen is approximately 21% in Earth's atmosphere.
What is not considered a greenhouse gas in the Earth's atmosphere?
Oxygen is not considered a greenhouse gas in the Earth's atmosphere.
What is the percent abundance of argon gas?
It accounts ofr 0.934% by volume, of the earth's atmosphere.
Which element is considered the most versatile element in living organisms and why?
Carbon is considered the most versatile element in living organisms because of its ability to form strong covalent bonds with other carbon atoms and a variety of other elements. This allows carbon to form complex molecules with diverse structures and functions, making it essential for the diversity of life on Earth.
What phylum contains seventy five percent of organisms on earth?
Insects
What percentage of organisms on Earth are considered to be carbon based?
It is 99%
What makes up 50 percent of all organisms?
Bacteria make up 50 percent of all organisms on Earth. They are found in almost every environment, from soil to water to deep in the Earth's crust, and play crucial roles in nutrient cycling and in the health of ecosystems.
How much percent of earth's dry land is still available and how much percent is covered with organisms?
Depends on what you mean?Do you mean only on dry land? Or are you asking to include sea life as well?I can tell you about the percentage for the entireEarth's mass, however; meaning it calculates the entire population of the Earth including the sea.The entire Earth's population of living organisms' number fluctuates daily as some organisms only live for a day; but on average, about 76% of the Earth's mass is live organisms. (This is including aquatic life.)
What are the most numerous organisms on earth?
Bacteria are generally considered the most numerous organisms on Earth. They are found in virtually every environment and play crucial roles in ecosystems, from aiding in nutrient recycling to influencing human health.
What are considered the oldest multicellular organisms on earth?
One of the oldest multicellular organisms on Earth are believed to be the Ediacaran biota, which lived around 635 to 541 million years ago. Fossils of these ancient organisms show evidence of complex multicellularity, though their exact classification and relationships to modern organisms are still debated among researchers.
Why is fresh water considered a limited resource?
The reason why fresh water is considered a limited resource is because the large majority of water on earth is saltwater. 97 percent of the earth's water supply is saltwater and only 2.5 percent is fresh water, some of which is snow and ice.
Can earth be considered as capacitor?
No, Earth cannot be considered a capacitor. A capacitor is a device that stores electrical energy between two conductive plates separated by an insulator. Earth is a mass of land and water on which organisms live and does not function as a capacitor in the traditional sense.
What kind of ecosystems covers most of the earth surface?
The ocean is considered an ecosystem. 70 percent of the earth is made up of ocean water.A+-- Marine
What group of organisms alive today are most similar to the first cells on earth?
Archaea are considered to be the group of organisms most similar to the first cells on Earth. They are single-celled microorganisms that have simple cell structures and thrive in extreme environments, similar to the conditions present on early Earth.
Are archaebacteria simple or complex?
Archaebacteria are some of the oldest organisms living on Earth. They are considered simple because of their external body structure.
What percent of water on the earth is shared by all living things?
Approximately 0.3% of all water on Earth is freshwater available for use by all living things, including humans, animals, and plants. The majority of Earth's water is saline and found in oceans and seas, not suitable for consumption by most living organisms.
