Question

Insectivorous plants trap insects to __________.

• A. Meet their potassium requirements
• B. Meet their nitrogen requirements
• C. Meet their phosphorous requirements
• D. Meet their oxygen requirements

Answer 1

The correct option is B Meet their nitrogen requirements

Insectivorous plants trap and digest insects and other small animals to obtain the nitrogen that is required for their growth. Most plants absorb enough nitrogen from nitrates in the soil but as the insectivorous plants live in nitrate-deficient bogs, they need to fulfill their nitrogen demand by digesting the prey instead.

So the correct option is 'Meet their Nitrogen requirements'
