If an insect has bark-like colour and escapes predators, which process will this help?
Answer and explanation
Correct answer: Natural selection
The governing concept is natural selection acting on an advantageous adaptation. Bark-like colour provides camouflage, making the insect less visible to predators. If it survives more often, it has a greater chance to reproduce and pass any heritable basis of that colour to its offspring. Over generations, the trait may become more frequent in the population. Excretion, digestion and transpiration are physiological processes and do not explain this survival advantage.
