Define 'Behavioural Adaptation'.

Back

Behavioural adaptations are actions or behaviors that organisms perform to survive in their environments.

Front

What is 'Transpiration' in plants?

Back

Transpiration is the process by which water is absorbed by plant roots and then evaporated from the leaves into the atmosphere.

Front

What role do gills play in aquatic organisms like the periwinkle?
