Let's solve this step by step based on the image you've described. The worksheet is about "Living Things Vital Functions", and it asks students to identify and label the three main vital functions of living organisms.

🔹 Step 1: Identify the Three Vital Functions



All living things perform three vital functions:

1. Nutrition
2. Response (or Irritability)
3. Reproduction

These are the three key processes that all living organisms must carry out to survive.

So, fill in the top boxes with:
- Nutrition
- Response
- Reproduction

Now let’s complete the definitions under each.

---

🔹 Definitions:



#### 1. Nutrition:
> "It’s the process of ________ food into the ________ that we need and get ________."

Fill in:
> It’s the process of transforming food into the nutrients that we need and get energy.

🔹 So, the full sentence becomes:
> It’s the process of transforming food into the nutrients that we need and get energy.

---

#### 2. Response (Irritability):
> "Is the ability to ________ the ________ in the environment and ________ to them."

Fill in:
> Is the ability to detect the changes in the environment and react to them.

🔹 Full sentence:
> Is the ability to detect the changes in the environment and react to them.

---

#### 3. Reproduction:
> "Is the ability to ________ ____________."

Fill in:
> Is the ability to produce offspring.

🔹 Full sentence:
> Is the ability to produce offspring.

🔹 Step 2: Match Each Picture to the Correct Vital Function



Now, look at the six pictures and determine which vital function they represent.

#### Image 1: Squirrel eating corn
- This shows eatingNutrition
Answer: Nutrition

#### Image 2: Ants working together (possibly carrying food or building)
- This shows behavior in response to stimuli (e.g., finding food), but more importantly, it reflects social behavior and survival, but not directly reproduction.
- However, ants are responding to environmental cues (like food) → Response
Answer: Response

But wait — let’s analyze carefully.

Actually, this picture might be showing cooperation, but response is better here because ants detect food and react.

Alternatively, if it's showing movement toward food, that’s a response.

So: Response

#### Image 3: Chick hatching from an egg
- Clearly shows birthReproduction
Answer: Reproduction

#### Image 4: Deer running away from fire
- The animal is reacting to danger (fire) → Response
Answer: Response

#### Image 5: Koala eating eucalyptus leaves
- Eating → Nutrition
Answer: Nutrition

#### Image 6: Frog catching a fly with its tongue
- This is feeding behaviorNutrition
Answer: Nutrition

Wait! Let’s double-check:

But the frog is catching prey — yes, nutrition.

But what about response? Yes, the frog detects the fly and reacts — so both response and nutrition are involved.

However, the main focus of the image is feeding, so it's primarily nutrition.

But note: The task says “Write the correct vital function” — so pick the primary one.

So:
- Frog catching fly → Nutrition

But let’s re-evaluate:

- Squirrel eating: Nutrition
- Ants: Possibly Response (they're detecting food and reacting)
- Chick hatching: Reproduction
- Deer fleeing fire: Response
- Koala eating: Nutrition
- Frog catching fly: Nutrition

Wait — now we have:
- Nutrition: 3 images (squirrel, koala, frog)
- Response: 2 (ants, deer)
- Reproduction: 1 (chick)

That makes sense — the three functions are represented.

But let’s confirm the ant image: Are the ants responding to something?

Yes — they’re likely reacting to food or pheromones — so Response is correct.

Final Answers:



#### Top Boxes (Three Vital Functions):
1. Nutrition
2. Response
3. Reproduction

#### Definitions:
1. Nutrition:
> It’s the process of transforming food into the nutrients that we need and get energy.

2. Response:
> Is the ability to detect the changes in the environment and react to them.

3. Reproduction:
> Is the ability to produce offspring.

#### Below Pictures – Write the function under each:

1. Squirrel eating corn → Nutrition
2. Ants (working/interacting) → Response
3. Chick hatching → Reproduction
4. Deer running from fire → Response
5. Koala eating → Nutrition
6. Frog catching fly → Nutrition

📝 Summary Table:



| Picture | Vital Function |
|--------|----------------|
| Squirrel eating corn | Nutrition |
| Ants | Response |
| Chick hatching | Reproduction |
| Deer fleeing fire | Response |
| Koala eating | Nutrition |
| Frog catching fly | Nutrition |

Final Answer:



Top Box Labels:
- Nutrition
- Response
- Reproduction

Definitions:
1. Nutrition: transforming food into nutrients we need and get energy.
2. Response: detect changes in the environment and react to them.
3. Reproduction: produce offspring.

Under pictures:
1. Nutrition
2. Response
3. Reproduction
4. Response
5. Nutrition
6. Nutrition
