Insects have a high surface area to volume ratio, which could lead to rapid water loss. What structural adaptation primarily minimizes this risk?
Understand the Problem
The question is asking about a specific adaptation in insects that reduces water loss due to their high surface area to volume ratio. We need to identify the structural adaptation from the given options that serves this purpose.
Answer
Insects use a thick exoskeleton made of chitin covered by a waxy layer to minimize water loss.
Insects minimize water loss with a thick exoskeleton made of chitin covered by a waxy layer. This adaptation provides a barrier that reduces water evaporation from their body surface.
Answer for screen readers
Insects minimize water loss with a thick exoskeleton made of chitin covered by a waxy layer. This adaptation provides a barrier that reduces water evaporation from their body surface.
More Information
The waxy layer on the exoskeleton is crucial for preventing water loss. Some insects can also close their spiracles (respiratory openings) to further reduce water loss.
Tips
A common mistake is to only mention the exoskeleton without including the waxy layer, which is essential for its water-proofing function.
