Two Types of Coevolution
Coevolution is common among organisms participating in a mutual interaction. In mutualism, both the organisms benefit from each other. When coevolution occurs among mutually benefiting species, it is called mutualistic coevolution.
When coevolution is found among species that have negative effects on each other, it is called competitive coevolution. There are two kinds of interactions between species that can lead to competitive coevolution:
<span><span>Predation is when one organism kills and eats another organism. The prey is the species that gets eaten by the predator, which is of course the species that eats the prey.</span><span>Parasitism is when one organism benefits by damaging, but not killing, another organism. The parasitespecies benefits from this relationship, while the host species is negatively affected.</span></span>
Ruminant herbivores gain from the microflora in their gut through digestion of cellulose and in return, the microflora gets the nutrients from the ruminants. The shark doesn't benefit from the remora but the remora gets a free ride from the shark and it feeds on the leftovers from the shark's meal. The human host loses nutrients because the tapeworm gets to eat the food provided by the host. Cats provide shelter and food for the flea but the cat becomes anemic because of blood loss from its parasites.
Citizens of the World State are cremated when they die, so their bodies can be recycled and used as fertilizer. Their bodies aren't considered valuable, there are no funerals or grieving of the dead.
Hope this helps!
