Question

How do insects limit water loss? (3)

Accepted Answer

- small SA:vol ratio- smaller area for evaporation- reduces water loss by evaporation- spiracles close at rest- water cannot diffuse out- reduces water loss by evaporation- waterproof cuticle over chitin exoskeleton- longer diffusion pathway- reduces water loss by evaporation
