Show Answer Key & Explanations Step-by-step solution for: Minibeast Dichotomous Key worksheet
Let's solve this Animal Classification Key step by step using the flowchart and the images of minibeasts provided at the bottom.

Step 1: Understand the Flowchart



We have a decision tree to classify six minibeasts based on physical features:

- First question: *Has this minibeast got wings?*
- Yes → Go to "Has it got 8 legs?"
- No → Go to "Has it got legs?"

Then:
- If wings = Yes, then:
- Has it got 8 legs?
- Yes → Box A
- No → Box B

- If wings = No, then:
- Has it got legs?
- Yes → Then check: *Has it got a shell?*
- Yes → Box C
- No → Box D
- No → Then go to: *Has it got a furry body?*
- Yes → Box E
- No → Box F

So, we need to place each animal into one of the 6 boxes based on these decisions.

Step 2: Identify the Animals



From left to right in the image:

1. Slug – no wings, no legs (it moves with a muscular foot), no shell (soft body)
2. Butterfly – has wings, 6 legs
3. Beetle – has wings, 6 legs
4. Bee – has wings, 6 legs
5. Spider – has wings? No, but has 8 legs
6. Snail – no wings, has legs (muscular foot), has a shell

Wait — let’s clarify:

Actually, snails do have a shell, and they move with a muscular foot (which counts as a leg in some contexts). But technically, snails have one large foot, not multiple legs like insects or spiders.

Similarly, slugs are snails without shells.

Let’s analyze each animal carefully.

Animal Analysis



#### 1. Slug
- Wings? → No
- Legs? → No (no jointed legs; just a single foot)
- Shell? → No
- Furry body? → No (smooth, slimy)

→ Path: No wings → No legs → No shell → So goes to "No" branch of shell → No → Then check: Has it got a furry body? → No → So box for No fur under "No legs"

But wait: After “No legs”, the next question is “Has it got a shell?”
- Slug: No shell → so goes to No → then Has it got a furry body?No → so final box: No fur, no legs, no shell

This corresponds to the bottom-right box labeled "No" after "Has it got a shell?" → then "No" after "furry body?"

So Slug → Bottom-right box (No legs, no shell, no fur)

---

#### 2. Butterfly
- Wings? → Yes
- 8 legs? → No (6 legs)
→ So goes to "No" under "Has it got 8 legs?" → that box is the one on the right under the "wings = yes" branch.

So Butterfly → Box: Yes wings, No 8 legs

---

#### 3. Beetle
- Wings? → Yes (hard wing covers, but still wings)
- 8 legs? → No (6 legs)
→ Same as butterfly → Box: Yes wings, No 8 legs

But wait — can two animals go in the same box?

Yes — if they match the same criteria, they can share a box.

But let’s check all.

---

#### 4. Bee
- Wings? → Yes
- 8 legs? → No (6 legs)
→ Also goes to Yes wings, No 8 legs

So Butterfly, Beetle, Bee all go to the same box: Yes wings, No 8 legs

But there are only two boxes under "Yes wings": one for "Yes 8 legs", one for "No 8 legs".

So three animals in one box? That’s fine — the key allows multiple animals per box.

But let’s check if any of them have 8 legs.

No — butterflies, bees, beetles all have 6 legs.

So yes — all three go to "Yes wings, No 8 legs"

---

#### 5. Spider
- Wings? → No
- Legs? → Yes (8 legs)
- Shell? → No (no shell)
→ So path: No wings → Yes legs → Has it got a shell? → No → So goes to "No" under "Has it got a shell?"

So Spider → Box: No wings, Yes legs, No shell

That’s the box on the right side of "Has it got a shell?" → "No"

---

#### 6. Snail
- Wings? → No
- Legs? → Yes (muscular foot — considered a leg in this context)
- Shell? → Yes
→ So path: No wings → Yes legs → Has it got a shell? → Yes → So goes to "Yes" under "Has it got a shell?"

So Snail → Box: No wings, Yes legs, Yes shell

---

Now let’s list the boxes:

Box Labels from Flowchart



Let’s label the boxes:

1. Top-left box: After "Has it got a furry body?" → Yes → This is for animals with no wings, no legs, no shell, furry body

2. Second box (top-left, No): After "Has it got a furry body?" → No → For no wings, no legs, no shell, not furry

→ This is where Slug goes

3. Middle-left box: After "Yes wings", "Yes 8 legs" → This is for wings + 8 legs

→ Who has wings and 8 legs? Spider? No — spider has no wings.

Wait — no animal in the list has both wings and 8 legs

Let’s double-check:

- Butterfly: wings, 6 legs → No
- Beetle: wings, 6 legs → No
- Bee: wings, 6 legs → No
- Spider: no wings, 8 legs → No
- Snail: no wings, no legs, shell → No
- Slug: no wings, no legs, no shell → No

So no animal has wings AND 8 legs

So the "Yes wings, Yes 8 legs" box will be empty

But maybe I made a mistake.

Wait — spiders don’t have wings, so no animal has both.

So the "Yes wings, Yes 8 legs" box remains empty.

But what about beetles? They have wings (hard elytra), but 6 legs.

So only 6-legged insects have wings here.

So Butterfly, Bee, Beetle → all go to Yes wings, No 8 legs

So that box gets 3 animals

---

Final Assignment:



Let’s map each animal:

| Animal | Wings? | Legs? | 8 legs? | Shell? | Furry? | Box |
|------------|--------|-------|---------|--------|--------|-----|
| Slug | No | No | N/A | No | No | Box: No wings → No legs → No shell → No fur → Bottom-right box |
| Butterfly | Yes | Yes | No | No | No | Box: Yes wings → No 8 legs → Middle box (right side) |
| Beetle | Yes | Yes | No | No | No | Same as above → Same box |
| Bee | Yes | Yes | No | No | No | Same → Same box |
| Spider | No | Yes | Yes | No | No | Box: No wings → Yes legs → No shell → Right box under "shell?" → No |
| Snail | No | Yes | N/A | Yes | No | Box: No wings → Yes legs → Yes shell → Right box under "shell?" → Yes |

Now, identify the boxes:

Let’s number them:

1. Box A: Yes wings → Yes 8 legs → Empty
2. Box B: Yes wings → No 8 legs → Butterfly, Beetle, Bee
3. Box C: No wings → Yes legs → Yes shell → Snail
4. Box D: No wings → Yes legs → No shell → Spider
5. Box E: No wings → No legs → Yes furry → Empty (no animal is furry)
6. Box F: No wings → No legs → No furry → Slug

---

Final Answer:



Place the animals in the boxes as follows:

- Box 1 (Yes wings, Yes 8 legs): Empty
- Box 2 (Yes wings, No 8 legs): Butterfly, Beetle, Bee
- Box 3 (No wings, Yes legs, Yes shell): Snail
- Box 4 (No wings, Yes legs, No shell): Spider
- Box 5 (No wings, No legs, Yes furry): Empty
- Box 6 (No wings, No legs, No furry): Slug

Explanation Summary



- The key uses a series of yes/no questions to classify animals.
- Start with wings → then branch based on legs, shell, or fur.
- Butterfly, bee, beetle all have wings and 6 legs → go to "Yes wings, No 8 legs"
- Spider has no wings, 8 legs, no shell → goes to "No wings, Yes legs, No shell"
- Snail has no wings, has legs (foot), has shell → "No wings, Yes legs, Yes shell"
- Slug has no wings, no legs, no shell, not furry → "No wings, No legs, No furry"
- No animal has wings and 8 legs → top middle box is empty
- No animal is furry → top-left box is empty

---

Final Placement:

- Top-left box (Yes, furry): Empty
- Top-right box (No, not furry): Slug
- Middle-left box (Yes wings, 8 legs): Empty
- Middle-right box (Yes wings, No 8 legs): Butterfly, Beetle, Bee
- Bottom-left box (No wings, legs, shell): Spider
- Bottom-right box (No wings, legs, no shell): Snail

Wait — let’s recheck the diagram layout.

Looking at the flowchart:

After "Has it got wings?" → split:

- Yes → "Has it got 8 legs?" →
- Yes → Box 1
- No → Box 2

- No → "Has it got legs?" →
- Yes → "Has it got a shell?" →
- Yes → Box 3
- No → Box 4
- No → "Has it got a furry body?" →
- Yes → Box 5
- No → Box 6

So the boxes are:

1. Box 1: Yes wings, 8 legs → Empty
2. Box 2: Yes wings, No 8 legs → Butterfly, Beetle, Bee
3. Box 3: No wings, Yes legs, Yes shell → Snail
4. Box 4: No wings, Yes legs, No shell → Spider
5. Box 5: No wings, No legs, Yes furry → Empty
6. Box 6: No wings, No legs, No furry → Slug

So:

- Box 1: Empty
- Box 2: Butterfly, Beetle, Bee
- Box 3: Snail
- Box 4: Spider
- Box 5: Empty
- Box 6: Slug

---

Final Answer:



Place the animals as follows:

- Box (Yes wings, 8 legs): Empty
- Box (Yes wings, 6 legs): Butterfly, Beetle, Bee
- Box (No wings, legs, shell): Snail
- Box (No wings, legs, no shell): Spider
- Box (No wings, no legs, furry): Empty
- Box (No wings, no legs, not furry): Slug
