Explanation:

• Option 1: Carbohydrates (e.g., glucose) provide immediate energy. In plants, cellulose (a carb) gives structural support; in insects, chitin (a carb) does too.
• Option 2: Nucleic acids (DNA/RNA) store genetic material, not carbs.
• Option 3: Lipids (not carbs) make up cell membranes’ structure, and fats (lipids) store energy long - term. So Option 1 is correct.

Answer:

The correct option is: They provide immediate energy and structural support to both plants and insects.
