• microbiology

• ecology

• biology

The study of the interrelationships that exist between organisms and their environment.

• ecology

• microbial ecology

• biology

The living together or close association of two dissimilar organisms. (usually two different species) Beneficial to both symbionts

• Symbiosis

• neutralism

• commensalism

The organisms that are together in symbiosis. (mutualistic relationships)

• symbionts

• atoms

• calcium

• ions

Symbiotic relationship in which neither symbiont is affected by the relationship

• neutralism

• symbiosis

• commensalism

Symbiotic relationship that is beneficial to one symbiont and no consequence to the other. ( ex. any indedigenous microflora of humans are commensals)

• mutualism

• commensalism

• neutralism

• parasitism

Living organism that harbors another living organism

• host

• pathogen

• microbe

• parasite

symbiotic relationship that is beneficial to both symbionts (eg. the relationship is mutually beneficial)
