2. MICROBAL ASSOCIATIONS
2.1. SYMBIOTIC
2.1.1. Organisms live in close nutritional relationships required by one or both members.
2.1.1.1. MUTUALISM OBLIGATORY
2.1.1.1.1. • Dependent both members benefit.
2.1.1.2. COMMENSALISM
2.1.1.2.1. • The commensal benefits; other members not harmed.
2.1.1.3. PARASITISM
2.1.1.3.1. • Parasites are dependent and benefits; host harmed.
2.2. NONSYMBIOTIC
2.2.1. Organisms are free-living; relationships not required for survival.
2.2.1.1. SYNERGISM
2.2.1.1.1. •Members cooperate and share nutrients.
2.2.1.2. ANTAGONISM
2.2.1.2.1. •Some members are inhibited or destroyed by others.

3.1. PASSIVE DIFFUSION
3.1.1. Power by a concentration gradient; does not require metabolic energy
3.1.1.1. FACILITATED DIFFUSION
3.1.1.1.1. Requires uniports or channel protein.
3.1.1.2. OSMOSIS
3.1.1.2.1. Can occur with or without transport protein.
3.2. Determines what goes in and out of bacterium
