What distinguishes mutualism from commensalism in symbiotic relationships?
What distinguishes mutualism from commensalism in symbiotic relationships?
- In mutualism, organisms only benefit temporarily, while commensalism is a permanent relationship.
- Mutualism involves two species that occupy the same habitat, whereas commensalism does not.
- In mutualism, one species is harmed while the other benefits, unlike commensalism where no one is harmed.
- Both species benefit in mutualism, while in commensalism one is helped and the other is unaffected. (correct)
Which type of symbiotic interaction involves one organism stealing resources from another without causing harm to the host?
Which type of symbiotic interaction involves one organism stealing resources from another without causing harm to the host?
- Foricic
- Cleptoparasitism (correct)
- Inquilinism
- Aggressive parasitism
What is the primary characteristic of ectosymbionts?
What is the primary characteristic of ectosymbionts?
- They engage in a temporary symbiotic relationship.
- They live within the internal organs of another organism.
- They are located on the external surface of another organism. (correct)
- They require the host for their entire life cycle.

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).
