Animals:vertebrates and invertebrates worksheet - Free Printable

Let's solve each part of this Natural Science worksheet step by step and explain the answers.

1. Drag and drop in the correct place

We are given images of animals and their names:
- Dog
- Crocodile
- Spider
- Worm
- Octopus
- Shark

We need to match the name with the image.

Looking at the images (from left to right):

1. Dog → First image (German Shepherd) ✔
2. Worm → Second image (earthworm-like creature) ✔
3. Spider → Third image (eight-legged arachnid) ✔
4. Crocodile → Fourth image (reptile with long snout) ✔
5. Octopus → Fifth image (eight-armed marine animal) ✔
6. Shark → Sixth image (fish with pointed snout and fins) ✔

✔ So, the correct order is:
- Dog → 1st image
- Worm → 2nd image
- Spider → 3rd image
- Crocodile → 4th image
- Octopus → 5th image
- Shark → 6th image

2. Write the name of the animals in the correct place

We need to classify the animals into Vertebrates and Invertebrates.

> Vertebrates: Animals with a backbone (spine).
> Invertebrates: Animals without a backbone.

Let’s analyze:

- Dog → Mammal → has backbone → Vertebrate
- Crocodile → Reptile → has backbone → Vertebrate
- Spider → Arachnid → no backbone → Invertebrate
- Worm → Annelid → no backbone → Invertebrate
- Octopus → Cephalopod (mollusk) → no backbone → Invertebrate
- Shark → Fish → has backbone → Vertebrate

So:

| VERTEBRATES | INVERTEBRATES |
|-------------|---------------|
| Dog | Spider |
| Crocodile | Worm |
| Shark | Octopus |

✔ Final table:

| VERTEBRATES | INVERTEBRATES |
|------------------|------------------|
| Dog | Spider |
| Crocodile | Worm |
| Shark | Octopus |

3. Match

Match the diet types with the correct description:

- Carnivores → Eat meat ✔
- Herbivores → Eat plants ✔
- Omnivores → Eat meat and plants ✔

So:

- Carnivores → Eat meat
- Herbivores → Eat plants
- Omnivores → Eat meat and plants

✔ Matching:
- Carnivores ➔ Eat meat
- Herbivores ➔ Eat plants
- Omnivores ➔ Eat meat and plants

4. Write true or false

Let’s evaluate each statement:

#### ➤ Viviparous animals are born from an egg.

- False
- Viviparous animals give birth to live young (not eggs).
- Example: Dogs, humans, elephants.
- Animals that lay eggs are oviparous.

#### ➤ An elephant is a mammal.

- True
- Elephants have fur (though minimal), nurse their young, warm-blooded, etc. → all traits of mammals.

#### ➤ Mammals have fur.

- True (mostly)
- Most mammals have fur or hair at some stage.
- Some exceptions (like whales) have very little, but they are still classified as mammals.
- Generally accepted as true for educational purposes.

#### ➤ Reptiles are invertebrates.

- False
- Reptiles (like crocodiles, snakes, lizards) have backbones → they are vertebrates.

✔ Answers:

- Viviparous animals are born from an egg. → False
- An elephant is a mammal. → True
- Mammals have fur. → True
- Reptiles are invertebrates. → False

✔ Final Answer Summary

#### 1. Drag and Drop
- Image 1: Dog
- Image 2: Worm
- Image 3: Spider
- Image 4: Crocodile
- Image 5: Octopus
- Image 6: Shark

#### 2. Vertebrates vs Invertebrates

| VERTEBRATES | INVERTEBRATES |
|------------------|------------------|
| Dog | Spider |
| Crocodile | Worm |
| Shark | Octopus |

#### 3. Match

- Carnivores → Eat meat
- Herbivores → Eat plants
- Omnivores → Eat meat and plants

#### 4. True or False

- Viviparous animals are born from an egg. → False
- An elephant is a mammal. → True
- Mammals have fur. → True
- Reptiles are invertebrates. → False
