Answer

To categorize the Great Barrier Reef along the east coast of Australia, we need to analyze the options provided: population, community, ecosystem, and biome.

### Step-by-Step Solution:

1. **Understand the Great Barrier Reef**:
- The Great Barrier Reef is the largest coral reef system in the world, located off the coast of Australia. It consists of numerous coral reefs and marine life.

2. **Define the Options**:
- **Population**: This refers to a group of individuals of the same species living in a specific area. Since the Great Barrier Reef is home to many different species, this option is not applicable.
- **Community**: This is a group of different populations (different species) living in a particular area. While the reef does contain various species, it is more than just a community.
- **Ecosystem**: An ecosystem includes all the living (biotic) components and the non-living (abiotic) factors in a particular area. The Great Barrier Reef includes corals, fish, plants, and the surrounding water, making it an ecosystem.
- **Biome**: A biome is a larger ecological classification that encompasses multiple ecosystems. The Great Barrier Reef is a specific ecosystem rather than a biome.

3. **Identify the Correct Answer**:
- Given the definitions and characteristics of the Great Barrier Reef, the most accurate categorization is **ecosystem**. This includes both the living organisms and their physical environment.

### Final Answer:
The Great Barrier Reef along the east coast of Australia can be categorized as an **ecosystem**.
