Compare the mass of different objects in each picture using the provided weights.

Let's solve the problem step by step, comparing the masses of the different objects as shown in the images.

First Image: Cat and Horse

- Cat: 5 kg
- Horse: 76 kg

#### 1. The cat is ___________ than the horse.
Since the cat weighs 5 kg and the horse weighs 76 kg, the cat is lighter than the horse.
- Answer: lighter

#### 2. The car is ___________ kg less than the horse.
The image does not provide the mass of the car. However, we can infer that the car is on the other side of the balance and is heavier than the horse (since the horse is on the lower side). Let's denote the car's mass as \( C \).

From the balance:
\[ C > 76 \text{ kg} \]

Without the exact mass of the car, we cannot determine how much less the car is compared to the horse. This part seems incomplete or missing information.

#### 3. The horse is ___________ than the car.
Since the car is heavier than the horse, the horse is lighter than the car.
- Answer: lighter

Second Image: Carrot and Apple

- Carrot: 2.29 kg
- Apple: 3.65 kg

#### 4. The apple is ___________ than the carrot.
Since the apple weighs 3.65 kg and the carrot weighs 2.29 kg, the apple is heavier than the carrot.
- Answer: heavier

#### 5. The apple is ___________ kg more than the horse.
This question seems to be a mistake because the apple (3.65 kg) is being compared to the horse (76 kg), which is not logical given their vastly different masses. If this is a typo and should compare the apple to the carrot, we can calculate:
\[ \text{Difference} = 3.65 \text{ kg} - 2.29 \text{ kg} = 1.36 \text{ kg} \]
So, the apple is 1.36 kg more than the carrot.

If we assume the question is correct as written (comparing apple to horse), then:
\[ \text{Difference} = 76 \text{ kg} - 3.65 \text{ kg} = 72.35 \text{ kg} \]
So, the apple is 72.35 kg less than the horse, but this doesn't fit the "more than" format. Let's assume it's a typo and focus on the carrot comparison.

#### 6. The carrot is ___________ than the apple.
Since the carrot weighs 2.29 kg and the apple weighs 3.65 kg, the carrot is lighter than the apple.
- Answer: lighter

Final Answers:

1. The cat is lighter than the horse.
2. The car is [incomplete, missing information] kg less than the horse.
3. The horse is lighter than the car.
4. The apple is heavier than the carrot.
5. The apple is 1.36 kg more than the carrot (assuming typo).
6. The carrot is lighter than the apple.

Boxed Final Answer:

\[
\boxed{\text{lighter, incomplete, lighter, heavier, 1.36, lighter}}
\]
