Science / Geology / Symbiosis: A relationship between two species who live in close association but do not compete with each other or prey on one another. At least one of the species derives benefit from this association.


Science / Biology / Endosymbiosis: Theory that attempts to explain the origin of the DNA-containing mitochondria and chloroplasts in early eukaryotes by the engulfing of various types of bacteria that were not digested but became perma MORE


Science / Biology / Protista: The taxonomic Kingdom from which the other three eukaryotic kingdoms (Fungi, Animalia and Plantae) are thought to have evolved. The earliest eukaryotes were single-celled organisms that would today be MORE


Science / Biology / Mutualism: A form of symbiosis in which both species benefit. A type of symbiosis where both organisms benefit. The classic example is lichens, which is a symbiosis between an alga and a fungus. The alga provide MORE


Science / Biology / Parasitism: A form of symbiosis in which the population of one species benefits at the expense of the population of another species; similar to predation, but differs in that parasites act more slowly than predat MORE
