Match each type of symbiotic relationship with its corresponding real-world ecological interaction.

  • MutualismClownfish gain shelter within sea anemone tentacles while actively defending the anemone against polyp-eating fish.
  • CommensalismBarnacles attach to the skin of a whale to feed on plankton as the whale swims, causing no harm or benefit to the whale.
  • ParasitismMistletoe taps into the vascular tissue of a host oak tree to siphon water and nutrients, stunting the tree's growth.

Cevap

Mutualism matches the clownfish and sea anemone interaction; Commensalism matches the barnacle and whale interaction; Parasitism matches the mistletoe and oak tree interaction.
Symbiotic relationships are defined by the net biological effect on both organisms: mutualism represents a positive-positive (+/+) interaction, commensalism represents a positive-neutral (+/0) interaction, and parasitism represents a positive-negative (+/-) interaction.

Adım Adım Çözüm

1
Evaluate the interaction between clownfish and sea anemones.
Both the clownfish (obtaining protection) and the anemone (defended from predators) gain measurable advantages.
An interaction where both species benefit is defined as mutualism.
2
Evaluate the interaction between barnacles and whales.
Barnacles gain a stable platform and constant food-bearing currents, while the whale is completely unharmed and unaffected.
An interaction where one species benefits without affecting the host is defined as commensalism.
3
Evaluate the interaction between mistletoe and oak trees.
Mistletoe draws water and essential minerals directly from the oak, weakening and depriving the host tree.
An interaction where one species feeds on and harms a living host is defined as parasitism.
