Explain with the help of an example how physical and biological components of the environment are interdependent.
The physical and the biological components of the environment are interdependent and cannot be separated. Any major change in the physical environment is bound to bring a change in the accompanying biological environment. For example, the development of soil takes years together and cannot be visualised through our senses. On the other hand, some changes are very sudden, like the changes brought about by the occurrence of an earthquake or volcano, etc.
