ACTIVITY 2: Select the correct answer for each animal according to their feeding habits.

We need to pick the right term for each animal based on what it eats.

- Spider → eats insects (meat) → Carnivore ✔

Row 2:
- Monkey → eats fruits, leaves, sometimes insects or small animals → Omnivore ✔
- Cheetah → eats only meat → Carnivore ✔
- Caterpillar → eats leaves/plants → Herbivore ✔

Now let’s match with the options given under each picture:

Under sheep: Herbivore / Carnivore → choose Herbivore
Under bear: Omnivore / Herbivore → choose Omnivore
Under spider: Omnivore / Carnivore → choose Carnivore
Under monkey: Herbivore / Omnivore → choose Omnivore
Under cheetah: Carnivore / Omnivore → choose Carnivore
Under caterpillar: Carnivore / Herbivore → choose Herbivore
