In another article, the author of "The Lives of a Cell," starts out by describing the decontamination process that astronauts who came back from the moon go through. It is feared that they brought back some kind of harmful microbes or life-forms. However, he goes on to say that although people tend to have a fear to these microbes, "most of the associations between the living things we know about are essentially cooperative ones." Again, he emphasizes that each living thing is dependent on each other, and this includes microbes. He also write that organisms such as bacteria and fungi serve as models that the biologists could study because they have relationships that are similar to the social interactions between animals. Bacteria have symbiotic relationships with insects when they live in their tissues as do anemones and fishes.
