Yes, because:
1. Proteins are made up partly of Nitrogen. Without Proteins, your cells will lack enough nourishment to repair itself or to build new tissues.
2. Nitric Oxide is made up of Nitrogen. Without Nitric Oxide, your cells will have difficulty communicating with each other.
3. Urea is made up of Nitrogen. Without Urea, you cannot remove damaged and used proteins from your body - and this causes the formation of toxins.
4. Enzymes are partly made up of Nitrogen. Without Enzymes, simple acts, such as food metabolism, would take 200 years to complete.
5. Plants require Nitrogen. When plants don't have nitrogen, they fail and this disrupts the food chain.

Answer:
Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life; since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term.
