Free nitrogen is in the air but fixed nitrogen is in the soil.

OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants. fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.
Yes it is.

No. Plants that belong to the family Leguminosae (legumes) are nitrogen fixers. Peas and beans are examples.
The fixing of nitrogen is an important part of the nitrogen cycle. Nitrogen fixing bacteria fix the nitrogen back into the atmosphere.
Nitrogen needs to be fixed before it is used by plants.
They are capable of converting atmospheric nitrogen into nitrogen that can be used by plants. They make the soil better.
