Educational worksheet for sorting animals into carnivore, herbivore, and omnivore categories using a Venn diagram.

To solve this task, we need to sort the animals based on their diets into a Venn diagram with three sections: Carnivore (meat-eaters), Herbivore (plant-eaters), and Omnivore (eaters of both meat and plants).

Let’s go through each animal one by one and decide which group they belong to.

---

1. Reindeer – Eats lichen, moss, grass → Plant-based diet → Herbivore

2. Giraffe – Eats leaves from trees → Plant-based diet → Herbivore

3. Dog – Can eat meat and plant-based foods (like grains in dog food) → Both → Omnivore

4. Polar Bear – Mainly eats seals and other meat → Meat-based diet → Carnivore

5. Pig – Eats roots, fruits, insects, sometimes small animals → Both → Omnivore

6. Dolphin – Eats fish and squid → Meat-based diet → Carnivore

7. Badger – Eats worms, insects, fruits, nuts → Both → Omnivore

8. Frog – Eats insects, worms → Mostly meat → Carnivore

9. Rhinoceros – Eats grass, leaves, twigs → Plant-based diet → Herbivore

Now let’s group them:

- Carnivores: Polar Bear, Dolphin, Frog
- Herbivores: Reindeer, Giraffe, Rhinoceros
- Omnivores: Dog, Pig, Badger

These groups fit perfectly — no overlaps needed beyond what the Venn diagram allows (since it’s set up for mutual exclusivity here, even though biologically some animals might blur lines, we’re going by standard classification for school level).

Final Answer:
Carnivore: Polar Bear, Dolphin, Frog
Herbivore: Reindeer, Giraffe, Rhinoceros
Omnivore: Dog, Pig, Badger
