Educational worksheet on vertebrates and invertebrates for natural science learning.

Task: Solve the problem and explain the solution

The worksheet focuses on vertebrate and invertebrate animals, their classifications, feeding habits, and some true/false statements. Let's solve each part step by step.

#### 1. Drag and drop in the correct place.

We are given images of animals and need to match them with their names:

- Dog: The image shows a dog.
- Crocodile: The image shows a crocodile.
- Spider: The image shows a spider.
- Worm: The image shows a worm.
- Octopus: The image shows an octopus.
- Shark: The image shows a shark.

Solution:
- Dog → First image (dog)
- Worm → Second image (worm)
- Spider → Third image (spider)
- Crocodile → Fourth image (crocodile)
- Octopus → Fifth image (octopus)
- Shark → Sixth image (shark)

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

We need to classify the animals into vertebrates (animals with backbones) and invertebrates (animals without backbones).

- Vertebrates: Dog, Crocodile, Shark
- Invertebrates: Spider, Worm, Octopus

Solution:
- Vertebrates: Dog, Crocodile, Shark
- Invertebrates: Spider, Worm, Octopus

#### 3. Match

We need to match the types of consumers (Carnivores, Herbivores, Omnivores) with their feeding habits.

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

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

#### 4. Write true or false

We need to evaluate the following statements as true or false:

1. Viviparous animals are born from an egg.
- False. Viviparous animals give birth to live young, not eggs. Examples include mammals like dogs and humans.

2. An elephant is a mammal.
- True. Elephants are mammals, which means they are warm-blooded, have fur, and nurse their young with milk.

3. Mammals have fur.
- True. Most mammals have fur or hair, although some, like whales, have very little or no visible fur.

4. Reptiles are invertebrates.
- False. Reptiles are vertebrates, meaning they have backbones. Examples include snakes, lizards, and crocodiles.

Solution:
- False
- True
- True
- False

Final Answer Summary:

1. Drag and drop:
- Dog → First image
- Worm → Second image
- Spider → Third image
- Crocodile → Fourth image
- Octopus → Fifth image
- Shark → Sixth image

2. Classification:
- Vertebrates: Dog, Crocodile, Shark
- Invertebrates: Spider, Worm, Octopus

3. Match:
- Carnivores → Eat meat
- Herbivores → Eat plants
- Omnivores → Eat meat and plants

4. True or false:
- False
- True
- True
- False
