symbiotic relationships?

Donovan Stallons: Me too.John R @ AOL.com

Shandi Wedge: I assume they evolved to have said symbiotic relationships. As so many others have pointed out, asking this in the religion section makes you appear to have less than sincere motives. Surely you realize that not all atheists are scientists studying the theory of evolution as well as the origins of the universe. I am a writer, and have no real reason to know the biological mechanism that provided certain animals with a symbiotic relationship.

Angelyn Ducas: The term symbiosis (from the Greek: συμ, sym, "with"; and βίοσίς, biosis, "living") commonly describes close and often long-term interactions between different biological species. The term was first used in 1879 by the German mycologist, Heinrich Anton de Bary, who defined it as: "the living together of unlike organisms".[2][3]The definition of symbiosis is in flux and the term has been applied to a wide range of biological interactions. The sy! mbiotic relationship may be categorized as being mutualistic, parasitic, or commensal in nature [4][5]. Others define it more narrowly, as only those relationships from which both organisms benefit, in which case it would be synonymous with mutualism. [6][7][8]Symbiotic relationships included those associations in which one organisms lives on another (ectosymbiosis, such as mistletoe), or where one partner lives inside another (endosymbiosis, such as lactobacilli and other bacteria in humans or zooxanthelles in corals). Symbiotic relationships may be either obligate, i.e., necessary to the survival of at least one of the organisms involved, or facultative, where the relationship is beneficial but not essential to survival of the organisms...Show more

Cedric Grimstead: same as sally

Brittanie Zakutney: Parasitism: A parasitic relationship is one in which one member of the association benefits while the other is harmed.Commensalism: Commensalism describes a relati! onship between two living organisms where one benefits and the! other is not significantly harmed or helped.Mutualism: The term Mutualism describes any relationship between individuals of different species where both individuals derive a fitness benefit....Show more
