Producers is the group of organism that is a source in the oxygen cycle.
Because then the organisms can make protein >_<
Few organisms can directly utilize atmospheric nitrogen gas.
Both carbon and nitrogen are found in the air as gases and are readily absorbed by the body. Unlike them, phosphorus is not in the air as a gas but rather moves slowly from deposits on land and sediments, to living organisms, and then back into the soil and water sediment.
Long term cycle: phosphorus is found in bedrock in the form of phosphate ions combined with a variety of elements. Phosphates are soluble in water and so can be dissolved out of rock. While dissolved, phosphates can be absorbed by photosynthetic organisms and passed into food chains. Short term cycle: wastes from living things are recycled by decomposers, which break down wastes and dead tissues and release the phosphates. This cycle is much more rapid.
All organisms are involved in the carbon cycle.
Mineral cycle involves replenishment of minerals. It takes place continuously.
nitrogen cycle
Very little new matter enters the Earth system, so exsisting matter must cycle continuously to for this planet to support life
it allows the water cycle to continuously vaporize the water into mist
The Calvin cycle is called a cycle because the catalysts are recycled and used again repeatedly and continuously (i.e. a circular process).
no. it is the other way around. living organisms are important to the rock cycle.

The water moves continuously through the water cycle.
