Prime purpose of this lecture is to present on Symbiosis and Homeostasis. Symbiosis is close and often long-term interaction between two different biological species. The tendency of the body to seek and maintain a condition of balance or equilibrium within its internal environment, even when faced with external changes. A simple example of homeostasis is the body’s ability to maintain an internal temperature around 98.6 degrees Fahrenheit, whatever the temperature outside.
