The layer where organisms can exist on the surface of the earth?
Organisms can exist on the surface of the earth in the biosphere, which includes all regions of land, water, and air where living organisms are found. The biosphere is where plants, animals, and other life forms interact with each other and with their physical environment.
The energy used by a living organism on earth comes from?
The energy used by a living organism on Earth primarily comes from the sun through photosynthesis. Plants and other photosynthetic organisms convert sunlight into chemical energy in the form of sugars, which is then used by other organisms through the food chain. Some organisms also obtain energy through consuming other organisms.
What percentage of Earth's fresh water?
Of all the water on Earth, around 2.75% of it is fresh drinking water.
Which earth system can you find animals?
Animals--along with plants, fungi and all other living organisms--are found in earth's biosphere. This simply refers to everything on the planet which is alive. All organisms in the biosphere are dependant on and connected to each other and the rest of earth's systems. Other earth systems include the atmosphere, geosphere and hydrosphere. Could there be a biosphere if any one of these systems were eliminated?
What is earth and life science?
Earth and life science is a branch of science that focuses on studying the interactions between Earth's systems and the living organisms that inhabit it. It examines topics such as geology, meteorology, ecology, and biology to better understand how the Earth and living organisms coexist and influence each other.
How much of all fresh water on Earth can be used by people and other land organisms?
The amount of Earth's water that is usable as a freshwater resources can vary. There is a very large percentage of freshwater available, but much of it is unobtainable.
What scientists study how people and the earth affect each other?
Ecologists study how living organisms and the earth interact with each other.

What advantage does a salt water organism have over a fresh water or terrestrial organism?
A salt water has an advantage over other organisms because the earth is made of more salt water then it is fresh water or land. This gives it more space to live and reproduce.
What group of organisms occupied most of the Earth's history?
Bacteria, Protazoans, and other microscopic organisms.

How much percent of fresh water lies on earth?

To anser your question directly though, 100% of the fresh water we know about is on Earth. There is some water on other celestial bodies, but I wouldn't exactly call it fresh water.
Where is the first living organism on earth in air or land water atmosphere?
The first living organisms on earth were a type of aquatic photosynthetic bacteria called cyanobacteria (blue-green algae). These organisms formed structures called stromatolites. These organisms did not become extinct and still exist in both salt and fresh water environments.
Why does people need fresh water in other countries?
Fresh clean water is needed by animals including people for health. If the water available is not fresh or clean it may carry organisms or txins that will be harmful. Some countries have a shortage of fresh water for various reasons. The population of the country may be too large to be supported by the natural water resource, the water may be wasted or polluted by bad practices.
