There are many cycles in biology including cycles that occur inside organisms such as the cardiac cycle, calvin cycle and the krebs cycle. There are also biological cycles that occur around us in the outside world such as the carbon cycle and the nitrogen cycle. I have decided to focus my essay on the biological cycles that occur inside organisms.
In depth summary's of the cycles included in this essay are: the cell cycle, the phosphorus cycle, the nitrogen cycle, the krebs cycle and the calvin cycle. This essay explores the importance and prevalence of cycles in biology.

The below mentioned article provides an essay on the Cell Cycle. Rudolf Virchow (1855, 1859) was the first to suggest that new cells are formed from the division of the pre-existing cells— omnis cellula e cellula (every cell is derived from a cell). In 1873, Strasburger similarly proposed that nuclei are formed from pre-existing ones.
