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.
Antarctica contains about 70% of the Earth's fresh water, and this is about 4% of Earth's water. Humans have access to about 1% of the accessible fresh water.
1% of of earth's water is usable fresh water
drinking water is bout 3%
By their selfisheness and their lack of ability to think about other organisms apon the earth.
Decomposers break down dead organisms which produce carbon dioxide and nutrients. These nutrients are then used by other organisms such as plants.
Some people believe the earth was first created 4.6 billion years ago, humans did not exist, nor did any other life forms. Humans didn't come into being until 15 million years ago, about 4.45 billion year's into earth's history.
true
Earth has a core of solid and liquid iron, a mantle of ultramafic rock, a crust of complex mineral compounds, and an atmosphere of nitrogen, oxygen, and other gases. Physical and chemical reactions on the Earth include the compound water (dihydrogen oxide or oxidane) in all three of its physical phases. Carbon-cycle (living) organisms utilize and alter the surface of the planet.
its less than one percent
Ecologists study how living organisms and the earth interact with each other.
If you are wondering what a paleontologist studies, well its not the Earth or organisms (which other people on this website put) they study fossils such as dinosaurs.
Insects are different from other organisms because they don't have any Lungs . Most organisms on earth have lungs other organisms do not , that is why they are different.
Nothing. There are no organisms on Earth that depend on humans for food. There might be some species that would die out naturally without human intervention.
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.
Bacteria, Protazoans, and other microscopic organisms.

Assuming you mean "How much of the water on Earth is fresh water", about 5% of the water on the Earth is fresh water, as opposed to about 95% salt water. 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.
Humans, apparently. We seem to be able to manage or disprupt the colonizations of other organisms at will. Other choice - molds.
othe organisms mustv compete with each other for food,water,and other things they need to survive
