• Bacteria alter the nitrogen into a form that plants are able to use.
• All of the above.

Biologists describe nutrients as moving through cycles because the substances

• start as simple organic forms that plants need. 
• provide “building blocks” and energy that organisms need.         
• are passed between organisms and the environment and then back to organisms.       
• are needed by organisms to carry out life processes.
