Today we explored the complicated nitrogen cycle. IF YOU MISSED CLASS TODAY you can add details about the nitrogen cycle to your notebook page 69. Be sure to include information about why organisms need nitrogen; what might happen in a community if all the nitrogen-fixing bacteria died; AND outline the major steps in the nitrogen cycle (illustrate the cycle). Tomorrow we bring the conversation of food and "you are what you eat" back into the chemical cycling discussion.

Most science pictures I post are found from assorted Facebook science pages... too numerous to cite specifically and downloaded for "just the right time"... I am sorry for the poor citation example I am setting.
