D. Organisms `rarr` Communities `rarr` Biosphere `rarr` Ecosystem `rarr` Biome

Answer

To determine the correct order of ecological hierarchy, we need to understand the different levels within an ecosystem. Here’s a step-by-step breakdown of the ecological hierarchy:

### Step 1: Understand the Levels of Ecological Hierarchy
The ecological hierarchy consists of several levels that describe the organization of life and the interactions within ecosystems. The main levels are:

1. **Organism Level**: This is the individual living entity, such as a single plant or animal.
2. **Population Level**: This includes a group of individuals of the same species living in a specific area.
3. **Community Level**: This encompasses all the different populations that live together in a defined area.
4. **Ecosystem Level**: This includes the community of living organisms along with the abiotic (non-living) components of their environment.
5. **Biome Level**: This refers to large geographical areas that have similar climate conditions and ecosystems.
6. **Biosphere Level**: This is the highest level, representing the global sum of all ecosystems, including interactions among biotic and abiotic components.

### Step 2: Identify the Correct Order
Based on the levels described, the correct order of ecological hierarchy is:

1. **Organism**
2. **Population**
3. **Community**
4. **Ecosystem**
5. **Biome**
6. **Biosphere**

However, in the context of the question, the focus is on the first four levels, which are:

- **Organism**
- **Population**
- **Community**
- **Ecosystem**

### Step 3: Conclusion
The correct order of ecological hierarchy is: **Organism → Population → Community → Ecosystem**.
