What is symbiosis?
Symbiosis is the relationship between two different organisms that live together in close association. Biologists added the term "close association" because they mean if one is separated from the other, one or both may die. There are three main types of symbiosis: mutualistic, commensal and parasitic. In a mutual relationship, both organisms benefit from their close association. For example, sea anemones and crabs live in a mutual relationship; the sea anemones protect the crab with it's stingers and remolds the shell to fit the crab. In return, the hermit crab allows the anemones to consume any portion of it's food. The anemones have a food supply and the crab has it's home fixed. In a commensal relationship, one organism benefits and the other is virtually unharmed. An example of this would be the relationship between cattle egrets and cattle or other livestock. As the livestock roam the fields, the insects that live in the grass or around the animals get excited and fly around, the egrets then catch and feed upon them. In a parasitic relationship, one organism benefits and the other is harmed. Much like the mosquito feeding off of human hosts.
What is Symbiotic Bacteria?
Symbiotic bacteria is mostly characterized as those that live in a mutual relationship with another host or organism(s). An example of a symbiotic bacteria would be the bacteria rhizobia; a type of nitrogen-fixing bacteria that lives within the root nodules of legumes.
