Nitrogen Cycle 2 The ______ cycle allows this element to change forms and be utilized by organisms found on planet Earth

Nitrogen Cycle- Atmosphere Nitrogen Gas 78% of the nitrogen found on Earth is in the atmosphere
Nitrogen Cycle- Lightning Nitric Acid Lightning is one mechanism that can change nitrogen into a usable form
Nitrogen Cycle- Roots Nitrogen-fixing bacteria Bacteria found on roots of legumes can fix nitrogen into a usable form
Nitrogen Cycle- Soil Other bacteria can convert fixed nitrogen into nitrates and nitrites for plants
Nitrogen Cycle- Nitrogen Decomposing When animals decompose, nitrogen is put back in the soil
