Questions and Answers

What is the difference between Batesian mimicry and Mullerian mimicry?

  • Both Batesian and Mullerian mimicry involve two harmful species mimicking each other but with different levels of toxicity.
  • Batesian mimicry involves two harmful species mimicking each other, while Mullerian mimicry involves a harmless species mimicking a harmful one.
  • Batesian mimicry involves a harmless species mimicking a harmful one, while Mullerian mimicry involves two harmful species mimicking each other. (correct)
  • Batesian mimicry involves two harmless species mimicking each other, while Mullerian mimicry involves a harmful species mimicking a harmless one.

    • What is the competitive exclusion principle?

  • The competitive exclusion principle states that two species competing for the same limited resource cannot coexist in the same ecological niche. (correct)
  • The competitive exclusion principle states that coevolution ensures the survival of multiple species within the same ecological niche.
  • The competitive exclusion principle states that two species can coexist in the same ecological niche by sharing resources equally.
  • The competitive exclusion principle states that competition between species in different niches leads to higher biodiversity.

    • What is aposematic coloration?

  • Aposematic coloration is a form of camouflage used by prey to blend into their environment.
  • Aposematic coloration is bright coloration that warns predators of an organism's defenses or toxicity. (correct)
  • Aposematic coloration is a strategy where organisms mimic harmful species for protection.
  • Aposematic coloration is a type of symbiotic relationship between two species for mutual benefit.
