Answer

To answer the question regarding the correct sequence of the levels of organization in biology, we need to follow the hierarchy from the smallest unit to the largest. Here’s the step-by-step breakdown:

1. **Organelles**: The smallest level of organization is organelles, which are specialized structures within a cell that perform specific functions (e.g., mitochondria, nucleus).

2. **Cells**: The next level is the cell itself, which is the basic unit of life. Cells are made up of organelles and can function independently.

3. **Tissues**: When similar cells group together to perform a common function, they form tissues. For example, muscle tissue is made up of muscle cells.

4. **Organs**: Different types of tissues come together to form an organ. For instance, the heart is an organ made up of muscle tissue, connective tissue, and nervous tissue.

5. **Organisms**: When multiple organs work together, they form an organism. An organism is a complete living entity, such as a human, plant, or animal.

6. **Population**: A population consists of individuals of the same species living in a specific area. For example, all the humans in a city form a population.

7. **Community**: A community is made up of different populations that live together in a defined area. For example, a forest community includes trees, animals, fungi, and microorganisms.

8. **Ecosystem**: An ecosystem includes all the living organisms (communities) in a particular area, along with the non-living components of their environment (like air, water, and soil).

9. **Biosphere**: The biosphere is the highest level of organization and includes all ecosystems on Earth. It represents the global sum of all ecosystems.

Now, putting this all together, the correct sequence of levels of organization is:
1. Organelles
2. Cells
3. Tissues
4. Organs
5. Organisms
6. Populations
7. Communities
8. Ecosystems
9. Biosphere
