Difficulty: MediumStructural Adaptations for Survival: Coloration, Camouflage, and Mimicry

Match each structural adaptation mechanism listed on the left with its corresponding biological example on the right.

  • Cryptic colorationThe peppered moth blending seamlessly against lichen-covered tree bark to avoid detection
  • Warning coloration (Aposematism)A highly toxic poison dart frog displaying vivid red and yellow body markings
  • Batesian mimicryA harmless hoverfly displaying yellow and black body stripes resembling a stinging wasp
  • Müllerian mimicryTwo distinct unpalatable butterfly species sharing nearly identical bright wing patterns

Answer

Cryptic coloration matches the peppered moth blending into tree bark; Warning coloration matches the toxic poison dart frog's bright markings; Batesian mimicry matches the harmless hoverfly resembling a wasp; Müllerian mimicry matches two unpalatable butterfly species sharing similar warning patterns.
Each adaptation mechanism correctly corresponds to its biological definition and ecological function: cryptic coloration hides organisms in their habitat; warning coloration advertises toxicity; Batesian mimicry protects a harmless species by copying a dangerous model; and Müllerian mimicry reinforces predator avoidance through shared warning signals among harmful species.

Step-by-Step Solution

1
Identify Cryptic Coloration
Matches the peppered moth blending into lichen-covered tree bark.
Cryptic coloration serves to conceal the organism from predators or prey by matching the background.
2
Identify Warning Coloration (Aposematism)
Matches the toxic poison dart frog displaying vivid red and yellow markings.
Warning coloration uses bright, conspicuous colors to signal distastefulness or dangerous defenses.
3
Distinguish between Batesian and Müllerian Mimicry
Batesian mimicry pairs the harmless hoverfly with the wasp. Müllerian mimicry pairs the two unpalatable butterfly species.
Batesian mimicry involves a harmless (palatable) mimic copying a harmful model, whereas Müllerian mimicry involves multiple harmful (unpalatable) species sharing a common warning appearance.
