Answer

To answer the question regarding the biological levels of organization of living things arranged from the simplest to the most complex, we can break it down into several steps:

### Step-by-Step Solution:

1. **Identify the Levels of Organization**: The biological levels of organization are typically categorized as follows:
- **Cells**: The basic unit of life.
- **Tissues**: Groups of similar cells that perform a specific function.
- **Organs**: Structures made up of different types of tissues working together.
- **Organ Systems**: Groups of organs that work together to perform complex functions.
- **Organisms**: Individual living entities that can function independently.
- **Populations**: Groups of organisms of the same species living in a specific area.
- **Communities**: Different populations that live together in a defined area.
- **Ecosystems**: Communities interacting with their physical environment.
- **Biosphere**: The global sum of all ecosystems, representing the zone of life on Earth.

2. **Arrange from Simplest to Most Complex**: Based on the definitions:
- Start with **Cells** (simplest).
- Move to **Tissues**.
- Then to **Organs**.
- Followed by **Organ Systems**.
- Next is **Organisms**.
- Then **Populations**.
- After that, **Communities**.
- Then **Ecosystems**.
- Finally, the **Biosphere** (most complex).

3. **Conclusion**: The correct order from simplest to most complex is:
- Cells → Tissues → Organs → Organ Systems → Organisms → Populations → Communities → Ecosystems → Biosphere.

### Final Answer:
The biological levels of organization of living things arranged from the simplest to the most complex are:
**Cells → Tissues → Organs → Organ Systems → Organisms → Populations → Communities → Ecosystems → Biosphere.**
