Study Notes
Symbiosis
- Symbiosis is the association between two or more species for a prolonged period of time.
- Symbiosis can be permanent or temporary.
- Obligatory symbiosis: one or more symbionts cannot live without the other.
- Facultative symbiosis: one or more symbionts can live independently.
Types of Symbiosis
- Mutualism: Both species benefit.
- Commensalism: One species benefits, the other is unaffected.
- Parasitism: One species benefits, the other is harmed.
- Inquilinism: One species lives in another's shelter.
- Foretic: One species travels on another.
- Cleptoparasitism: One species steals resources from another.
Symbiotic Location
- Ectobiont: Lives on the surface of another organism (e.g., on skin, gills).
- Endobiont: Lives inside another organism (e.g., intestines, tissues).
Other Factors
- Spatial Location is important for distinguishing the types of symbiosis.
- Benefits/Effects: Species may benefit, be unharmed, or be harmed.
- Specific examples: Gobies and shrimp, Nematodes and insects can be mutually beneficial or parasitic
- Aggressive/Passive: symbiosis can involve aggression or stealth depending on the participating organisms
- Life Cycle: Symbiosis can occur throughout a life cycle, part of it, or none of it.
- Competition Avoidance: The relationship can help organisms avoid competition (especially in juveniles).
