4th-science-ps05-animal adaptations worksheet - Free Printable

Let's solve this 4th Grade Science – Animal Adaptations worksheet step by step.

---

Part I: Give two examples for each of the following.

#### 1. Arboreal animals
*Animals that live in trees.*
✔ Examples:
- Squirrel
- Monkey

> ✔ *These animals are adapted to climbing and living in trees (e.g., strong limbs, grasping tails).*

---

#### 2. Animals that undergo hibernation
*Animals that sleep through winter to save energy.*
✔ Examples:
- Bears
- Ground squirrels

> ✔ *They lower body temperature and metabolism during cold months.*

---

#### 3. Carnivores
*Meat-eating animals.*
✔ Examples:
- Lion
- Tiger

> ✔ *They have sharp teeth and claws for hunting prey.*

---

#### 4. Scavengers
*Animals that eat dead animals (carcasses).*
✔ Examples:
- Vulture
- Hyena

> ✔ *They help clean up the environment by consuming dead animals.*

---

#### 5. Parasites that live inside the host’s body
*Internal parasites.*
✔ Examples:
- Tapeworm
- Roundworm

> ✔ *They live inside the digestive tract or other organs of hosts like humans or animals.*

Part II: Look at the pictures and choose the odd one out.

We have two rows of images. Let’s analyze each row.

---

#### Row 1:
1. Camel → Desert adaptation (humps store fat, long eyelashes protect from sand)
2. Yak → Lives in high-altitude mountains (cold climate), thick fur
3. Orca (Killer Whale) → Marine animal, lives in oceans
4. Polar Bear → Arctic, snow/ice habitat, thick fur and blubber

🔍 All except orca are land animals. Orca is a marine mammal.

✔ Odd one out: Orca (Killer Whale)
> Reason: It lives in water; others are terrestrial animals adapted to dry/cold land environments.

---

#### Row 2:
1. Chameleon → Camouflage, changes color, sticky tongue
2. Monkey → Not camouflaged; active, social, no special camouflage
3. Stick insect → Mimics a twig (camouflage)
4. Leaf insect → Mimics a leaf (camouflage)

🔍 Three animals (chameleon, stick insect, leaf insect) use camouflage as an adaptation.
But monkey does not rely on camouflage.

✔ Odd one out: Monkey
> Reason: It doesn’t use camouflage like the others; it relies on agility and social behavior.

---

✔ Final Answers:

#### Part I:
1. Arboreal animals: Squirrel, Monkey
2. Hibernation: Bear, Ground squirrel
3. Carnivores: Lion, Tiger
4. Scavengers: Vulture, Hyena
5. Internal parasites: Tapeworm, Roundworm

#### Part II:
- Row 1: Orca (Killer Whale) — odd one out
- Row 2: Monkey — odd one out
