At least 90 percent of the water that returns to the atmosphere from terrestrial ecosystems does so through?
transpiration in plants
Which organisms convert nitrogen into a form that is usable by humans?
Bacteria =========================== Specifically a particular type of bacteria that live in nodules on the roots of certain plants (eg the Legume family) called "Nitrogen Fixing Bacteria" . Not other bacteria decompose organic material and release nitrogen back into the atmosphere.
What is the role of the ocean in the carbon cycle?
Organisms such as protozoans, bacteria, and plants use photosynthesis to pull in CO2 from the atmosphere, releasing oxygen as a by product of the photosynthetic process.
What kind of organism converts nitrogen into a usable form of plants?
Bacteria
Oxygen is supplied to the atmosphere by what?
Plants

Gas makes up 78 percent of your atmosphere but can be used by plants only when transformed by bacteria first?
Nitrogen. The bacterial transformation is needed to break the triple bonds of diatomic atmospheric nitrogen, something plants can't do, so these bacteria fix the nitrogen into a usable form in exchange for plant sugar

What atmospheric gas can only be used by plants when transformed by bacteria first?
Nitrogen
When there is not enough nitrogen in the atmosphere for plants how do the plants get it?
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
How does nitrogen get from organisms back into the atmosphere?
Nitrogen used by plants and animals is returned to the atmosphere by the action of bacteria. Bacteria break down proteins to obtain energy, releasing nitrogen back into the air in the process.
What kind of organisms can remove nitrogen from the atmosphere bacteria plants mammals or fish?
Certain plants are nitrogen fixers. Alfalfa is one.
Why is rhizobi a helpful bacteria?
Rhizobia are known as nitrogen fixation bacteria. Nitrogen is an essential element for plants and it is plentiful in the atmosphere but in a form that is inaccessible to plants. Rhizobia can convert atmospheric nitrogen into a form that plants can uptake through their roots.
Nitrogen in the atmosphere must be fixed before it can be used by plants. Atmospheric nitrogen is fixed by?
bacteria and lighntning

How is nitrogen part of the biosphere?
It's continuously processed in the nitrogen cycle. In broad outline nitrogen in the atmosphere is fixed by bacteria so that it's available to plants making protein. This protein is consumed by animals and plants or returned to the atmosphere as methane. The plant nitrogen is converted to animal protein which is eventually returned to the atmosphere by bacteria.
