Living and Nonliving Things - Free Printable

Problem Overview:

The task is to classify objects as living or nonliving based on certain criteria. The criteria provided are:
1. Does it breathe?
2. Does it eat?
3. Does it move?
4. Does it reproduce?

The objects listed in the image are:
1. A mosquito
2. A clock
3. A bird
4. A flower
5. A snowflake

Solution Approach:

To solve this problem, we need to analyze each object against the given criteria and determine whether it is living or nonliving.

#### Criteria for Living Things:
- Breathing: Living things typically require oxygen for cellular respiration.
- Eating: Living things need to consume energy (food) to survive.
- Moving: Living things can move, either independently or through growth.
- Reproducing: Living things have the ability to produce offspring.

#### Criteria for Nonliving Things:
- Nonliving things do not meet any of the above criteria.

- Does it reproduce? Yes, mosquitoes lay eggs.
- Living? Yes

#### 2. Clock
- Does it breathe? No, a clock does not breathe.
- Does it eat? No, a clock does not consume energy.
- Does it move? No, a clock does not move independently.
- Does it reproduce? No, a clock cannot produce offspring.
- Living? No

#### 3. Bird
- Does it breathe? Yes, birds breathe using lungs.
- Does it eat? Yes, birds consume food.
- Does it move? Yes, birds fly, walk, and swim.
- Does it reproduce? Yes, birds lay eggs.
- Living? Yes

#### 4. Flower
- Does it breathe? Yes, flowers perform photosynthesis, which involves gas exchange.
- Does it eat? No, flowers do not consume food but obtain nutrients from soil and sunlight.
- Does it move? No, flowers do not move independently but can grow.
- Does it reproduce? Yes, flowers produce seeds.
- Living? Yes

#### 5. Snowflake
- Does it breathe? No, a snowflake does not breathe.
- Does it eat? No, a snowflake does not consume energy.
- Does it move? No, a snowflake does not move independently.
- Does it reproduce? No, a snowflake cannot produce offspring.
- Living? No

Final Classification Table:

| Object | Does it breathe? | Does it eat? | Does it move? | Does it Reproduce? | Living? |
|-------------|------------------|--------------|----------------|--------------------|---------|
| Mosquito | Yes | Yes | Yes | Yes | Yes |
| Clock | No | No | No | No | No |
| Bird | Yes | Yes | Yes | Yes | Yes |
| Flower | Yes | No | No | Yes | Yes |
| Snowflake | No | No | No | No | No |

Final Answer:

\boxed{
\begin{array}{|c|c|c|c|c|c|}
