Answer

To answer the question regarding the biological levels of organization of living things arranged from the simplest to the most complex, we can follow these steps:

### Step-by-Step Solution:

1. **Organelles**: The simplest level of organization. Organelles are specialized structures within cells that perform specific functions (e.g., mitochondria, endoplasmic reticulum).

2. **Cells**: The basic unit of life. Cells are formed from various organelles working together. They can be unicellular (single-celled organisms) or multicellular (organisms made up of many cells).

3. **Tissues**: A group of similar cells that work together to perform a specific function. For example, muscle tissue is made up of muscle cells.

4. **Organs**: Structures made up of different types of tissues that work together to perform specific functions. For example, the stomach is an organ that aids in digestion.

5. **Organ Systems**: Groups of organs that work together to perform complex functions. For example, the digestive system includes the stomach, intestines, liver, and pancreas.

6. **Organism**: An individual living entity that can function on its own. This can be a single-celled organism or a complex multicellular organism like a human.

7. **Population**: A group of organisms of the same species living in a specific area. For example, a population of humans in a city.

8. **Community**: Different populations of various species that live in the same area and interact with each other. For example, a community might include humans, dogs, cats, and birds in a neighborhood.

9. **Ecosystem**: A community of living organisms interacting with their physical environment (abiotic factors like soil, water, and climate).

10. **Biosphere**: The highest level of organization, encompassing all ecosystems on Earth. It includes all living beings and their relationships with the environment.

### Final Arrangement:
The correct sequence from simplest to most complex is:
- Organelles
- Cells
- Tissues
- Organs
- Organ Systems
- Organisms
- Populations
- Communities
- Ecosystems
- Biosphere
