word | symbiosis |
---|---|
definition | (1) The close living together of two different forms of life in a way that benefits both. (2) A cooperative relationship between two people or groups. |
eg_sentence | The lichen that grows on rocks is produced by the symbiosis of a fungus and an alga, two very different organisms. |
explanation | With its prefix sym-, “with,” symbiosis expresses the notion of cooperation between living things. Symbiotic associations are found throughout the plant and animal world. You may have read, for instance, of the little blackbird plover, which picks the teeth of the fierce African crocodile. Or the bird called the African honeyguide, which leads a little mammal called the ratel to a bees' nest, which the ratel, protected from the bees by its thick fur, then breaks open, and both it and the honeyguide feast on the honey. Or even our own bodies, which are home to millions of bacteria—especially the bacterium E. coli in our intestines—and neither we nor E. coli could live without the other. You can probably think of plenty of human relationships that could be called symbiotic as well |
