Show answer and explanation
Correct answer: (c) nitrogen
Explanation
Insectivorous (carnivorous) plants like Drosera, Nepenthes, Utricularia trap insects for food.
They grow in nitrogen-deficient soil and obtain nitrogen from the digested insects.
They still make food by photosynthesis, so insects supply only the missing nitrogen, not energy.
