Why do some plants eat insects?
Show answer & explanation
Answer: Poor soil lacks nutrients
Poor soil lacks nutrients ✓ — Correct! Carnivorous plants like Venus flytraps grow in nutrient-poor soil, especially lacking nitrogen. Catching insects supplements their diet. They still photosynthesize for energy—insects provide nutrients they can't get from poor soil!
Plants evolved to hunt — Wrong. Plants don't actively hunt like animals. They use passive traps and haven't evolved predatory behavior.
Insects damage the plants — Wrong. Plants trap insects for nutrition, not defense. They actually need insects to survive in poor soil.
