Parasitism is a relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life. [20] The parasite either feeds on the host, or, in the case of intestinal parasites, consumes some of its food. [21]
Ectosymbiosis is defined as a symbiotic relationship in which one organism lives on the outside surface of a different organism. [3] For instance, barnacles on whales is an example of an ectosymbiotic relationship where the whale provides the barnacle with a home, a ride, and access to food.

Syntrophy is often used synonymously for mutualistic symbiosis especially between at least two different bacterial species. Syntrophy differs from symbiosis in a way that syntrophic relationship is primarily based on closely linked metabolic interactions to maintain thermodynamically favorable lifestyle in a given environment.
Genome comparisons suggest a close relationship between mitochondria and Alphaproteobacteria. [72] Genome comparisons suggest a close relationship between plastids and cyanobacteria. [73] Many genes in the genomes of mitochondria and chloroplasts have been lost or transferred to the nucleus of the host cell.
