What is the main process of the nitrogen cycle?
2. Slide
60 seconds
Nitrogen gas makes up 78% of the air around us. Nitrogen is recycled through nature in a process called the 'nitrogen cycle'. Organisms such as bacteria turn nitrogen into forms that plants can use to grow.
The Nitrogen Cycle
3. Slide
60 seconds
Nitrogen Fixation: the process of converting nitrogen gas in the atmosphere into a form of nitrogen, such as ammonia, that can be used by plants and animals. Nitrification: the process of converting ammonia into nitrates, which can be used by plants as a source of nitrogen. Denitrification: the process of converting nitrates back into nitrogen gas, which is then released into the atmosphere.

Nitrogen gas makes up 78% of the air we breathe, but it is not usable by plants until it is converted to ammonia or nitrates by bacteria, lightning, or industrial processes. Nitrogen is an important component of proteins, DNA, and hormones in living organisms. Nitrogen is a necessary element for all living things, but it can be toxic to some organisms in high concentrations.

Brain break: Create a 3-dimensional drawing of a space station with at least five levels that includes a map of the interior of the station and a description of each level. Be sure to include information about the materials used to build the space station, the inhabitants of the station, and any special features it might have.
