Animal Adaptations Matching: Echolocation, Cryptic Coloration, Aposematism, Chemical Defences
Animal adaptations help species survive predators, hunt prey, and thrive in diverse habitats through specialized traits. This SEO article solves Q.55 matching question on key defenses with the correct answer and full option breakdowns.
Correct Answer
The correct option is (A)–(IV); (B)–(I); (C)–(III); (D)–(II). Echolocation defines bats, cryptic coloration suits canyon tree frogs, aposematism warns via skunks, and chemical defences characterize poison dart frogs.
Adaptation-Animal Matches
-
Echolocation (A) – Bats (IV): Bats emit ultrasonic pulses and interpret echoes for navigation and hunting in darkness, a sonar-like system unique to them among these options.
-
Cryptic coloration (B) – Canyon tree frog (I): These frogs blend into rocky canyon backgrounds through mottled gray-green skin, providing camouflage against predators.
-
Aposematism (C) – Skunks (III): Skunks display bold black-white stripes as warning coloration (aposematic signal) of their potent spray defense.
-
Chemical defences (D) – Poison dart frog (II): Vibrant poison dart frogs secrete toxic alkaloids through skin, making them unpalatable and lethal to predators.
Why Other Options Fail
-
Option 1: (A)–(IV); (B)–(II); (C)–(I); (D)–(III) Wrong: Cryptic not poison frogs (they’re aposematic); chemical defences not skunks primarily (they use spray, which is chemical but aposematism fits better).
-
Option 2: (A)–(I); (B)–(IV); (C)–(III); (D)–(II) Wrong: Bats don’t echolocate like frogs; cryptic not bats (they rely on sound).
-
Option 4: (A)–(IV); (B)–(I); (C)–(II); (D)–(III) Wrong: Aposematism not poison frogs here (they have chemical defences primarily matched separately).
Adaptation Strategies Overview
Echolocation aids nocturnal foraging, cryptic hides prey, aposematism advertises danger, chemical defences deter via toxins. These evolved convergently across amphibians and mammals for survival.
