Animal Classification (Vertebrates and Invertebrates) | Distance ... - Free Printable

Let's solve the worksheet step by step.

Q.1: Label the following diagram to classify animals.

We are given a flowchart that classifies animals based on whether they have a backbone or not.

#### Step 1: Understand the classification

- Animals with a backbone → Vertebrates
- Animals without a backbone → Invertebrates

So, we fill in:

- Have a backbone → Vertebrates
- Don't have a backbone → Invertebrates

Now, look at the animals shown:

1. Cow – has a backbone → Vertebrate
2. Bird (blackbird) – has a backbone → Vertebrate
3. Fish – has a backbone → Vertebrate
4. Snake – has a backbone → Vertebrate
5. Frog – has a backbone → Vertebrate

Wait! All five animals shown have backbones? But the diagram shows two branches: one for vertebrates and one for invertebrates.

But the image shows:
- Cow ✔ Vertebrate
- Bird ✔ Vertebrate
- Fish ✔ Vertebrate
- Snake ✔ Vertebrate
- Frog ✔ Vertebrate

But the diagram is meant to show both groups.

Hmm — this seems like an error in the image interpretation.

Wait — actually, looking again: The snake is green and looks like a worm, but it’s drawn as a snake. However, snakes are vertebrates.

But wait — maybe the green worm-like creature is meant to be an invertebrate, like an earthworm?

Ah! That’s likely the key.

Looking closely:
- The fourth animal is a green worm-like creature — this is probably an earthworm or snake? But if it's a worm, it's an invertebrate.

But it's drawn like a snake — which is a vertebrate.

But let's consider the context: the question is to classify animals into vertebrates and invertebrates.

So perhaps the fourth animal is an invertebrate — maybe a worm or snake?

Wait — snakes are vertebrates. So if it's a snake, it should go under "have a backbone".

But the diagram shows two branches — so one of the animals must be an invertebrate.

So likely, the fourth animal (the green one) is not a snake, but a worm — an invertebrate.

Similarly, the frog is a vertebrate.

Let’s re-express:

Animals shown:
1. Cow → vertebrate
2. Bird → vertebrate
3. Fish → vertebrate
4. Green worm-like animal → invertebrate (likely an earthworm or similar)
5. Frog → vertebrate

So only one invertebrate among five animals.

Thus, the correct labeling:

- Have a backbone → Vertebrates
- Don’t have a backbone → Invertebrates

Then, under Vertebrates:
- Cow
- Bird
- Fish
- Frog

Under Invertebrates:
- Green worm-like animal (e.g., earthworm)

So fill in the blanks:

```
Classifying Animals
↓
Have a backbone Don't have a backbone
↓ ↓
Vertebrates Invertebrates
↓ ↓
[Cow] [Bird] [Fish] [Frog] [Worm]
```

Wait — the diagram has five boxes below the two main branches.

So:
- Under Vertebrates: Cow, Bird, Fish, Frog
- Under Invertebrates: Worm (green one)

So the labels:

- First blank (left): Vertebrates
- Second blank (right): Invertebrates

Then below:
- Cow → Vertebrate
- Bird → Vertebrate
- Fish → Vertebrate
- Green worm → Invertebrate
- Frog → Vertebrate

So the fourth animal (worm) goes under Invertebrates, and the others under Vertebrates.

✔ So final answer for Q.1:

- Top left box: Vertebrates
- Top right box: Invertebrates
- Bottom boxes (from left to right):
- Cow → Vertebrate
- Bird → Vertebrate
- Fish → Vertebrate
- Green worm → Invertebrate
- Frog → Vertebrate

But since the boxes are under each branch, we label the boxes accordingly.

So:
- Under "have a backbone" → three boxes: Cow, Bird, Fish, Frog → all labeled Vertebrates?
No — the boxes are for the animals, but the category names go in the top boxes.

Wait — the diagram says:

```
Classifying Animals
↓
Have a backbone Don't have a backbone
↓ ↓
[_______] [_______]
↓ ↓
[Cow] [Bird] [Fish] [Worm] [Frog]
```

Actually, no — the animals are placed under the two branches.

Looking at the layout:

It appears that:
- The cow, bird, fish, frog are under the "have a backbone" branch
- The worm is under the "don't have a backbone" branch

But the frog is also a vertebrate, so it should be under "have a backbone"

Wait — the diagram shows all five animals below the two branches.

But likely:
- Cow, Bird, Fish, Frog → under have a backbone
- Worm → under don't have a backbone

And the two top boxes are for:
- Left: Vertebrates
- Right: Invertebrates

So:

Answer for Q.1:

- Left top box: Vertebrates
- Right top box: Invertebrates

Then:
- Cow → Vertebrate
- Bird → Vertebrate
- Fish → Vertebrate
- Frog → Vertebrate
- Worm → Invertebrate

So the worm is the only invertebrate here.

✔ Correct.

Q.2: Fill in the blanks with suitable words.

a) All living things are classified into five main groups called kingdoms.

> Actually, traditionally, living things are classified into five kingdoms:
> - Monera
> - Protista
> - Fungi
> - Plantae
> - Animalia

So: five

b) The two main groups of animals are vertebrates and invertebrates.

c) Vertebrates have backbones inside their bodies.

✔ Final Answers:

Q.1: Diagram Labels

- Top left box: Vertebrates
- Top right box: Invertebrates

- Below:
- Cow → Vertebrate
- Bird → Vertebrate
- Fish → Vertebrate
- Worm → Invertebrate
- Frog → Vertebrate

(All animals are already placed correctly in the diagram.)

Q.2: Fill in the blanks

a) All living things are classified into five main groups called kingdoms.

b) The two main groups of animals are vertebrates and invertebrates.

c) Vertebrates have backbones inside their bodies.

✔ Explanation Summary:

- Vertebrates have a backbone (spinal column), e.g., mammals, birds, fish, amphibians, reptiles.
- Invertebrates lack a backbone, e.g., worms, insects, snails.
- The worm in the diagram is an invertebrate, while the others are vertebrates.
- Living things are grouped into five kingdoms.
- Animals are divided into vertebrates and invertebrates based on the presence or absence of a backbone.
