At the bottom of this page you will find links to other pages where you can learn more about bacteria. I have written these pages to help beginners get started and to help advanced students find information they need. Please help by sending me an e-message containing your ideas for improvement.
Lets begin our study of bacteria by considering the balance of nature.
If there is food, some organism will eat it. If there is a place to live, some organism will live there. Every species has a great ability to produce offspring and its population expands until it runs out of food or it is limited by competition, its own waste products, or some other factor. Changes in climate or introduction of a new species from elsewhere can greatly affect the balance of nature. These simple sentences summarize the interactions of living things on earth.
