The tropical walking stick is an insect that uses camouflage as a method of avoiding predation. Camouflage is the adaptation that allows organisms to avoid detection by blending in with their surroundings. The walking stick has the coloration and body shape similar to a twig, making it particularly difficult for predators to spot when the insect remains stationary against a backdrop of real twigs. This form of defence helps it to be a successful primary consumer within its ecosystem.
The walking stick insect predominantly uses camouflage to avoid predation by blending in with its environment, which mimics twigs or branches. This adaptation helps it remain undetected by predators, ensuring its survival as a primary consumer. Therefore, the correct answer is (C) camouflage.
