Green plants need air to live.  Green plants use air to help make food in their leaves.

All green plants need sunlight to live.  The sunlight helps green plants make food.

The best-known plants which contribute to nitrogen fixation in nature, are in the legume family - Fabaceae, which includes such taxa as clover, beans, alfalfa, lupines and peanuts. They contain symbiotic bacteria called rhizobia within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants and this helps to fertilize the soil[1][3] The great majority of legumes have this association, but a few genera (e.g., Styphnolobium) do not. In many traditional and organic farming practices, fields are rotated through various types of crops, which usually includes one consisting mainly or entirely of clover or buckwheat (family Polygonaceae), which were often referred to as "green manure", since the other natural way of adding nitrogen to the soil was via animal waste products. The entire plant was often ploughed back into the field, thus not only adding more nitrogen, but also improving the soil's organic content and volume.
