Options

A. population species `to` community `to` ecosystem `to` biosphere
B. species `to`population `to` community `to` ecosystem `to` biosphere
C. species `to` population `to` biosphere `to` community `to` ecosystem
D. species `to` population `to` biosphere `to` ecosystem `to` community

Answer

To solve the question regarding the ecological hierarchy, we need to understand the correct sequence of levels in this hierarchy. Here’s the step-by-step solution:

### Step 1: Understand the Levels of Ecological Hierarchy
The ecological hierarchy consists of several levels that describe the organization of life. The simplest level starts with individual organisms.

### Step 2: Identify the First Level
The first level of the ecological hierarchy is the **Individual Organism**. This refers to a single member of a species.

### Step 3: Identify the Second Level
The second level is the **Population**. A population consists of individuals of the same species living in a specific area.

### Step 4: Identify the Third Level
The third level is the **Community**. A community includes different populations of various species that live together in a particular area.

### Step 5: Identify the Fourth Level
The fourth level is the **Ecosystem**. An ecosystem comprises the community of living organisms (biotic factors) interacting with their physical environment (abiotic factors).

### Step 6: Identify the Fifth Level
The fifth level is the **Biome**. A biome is a larger area that contains multiple ecosystems sharing similar climatic conditions.

### Step 7: Identify the Final Level
The final level is the **Biosphere**. The biosphere includes all ecosystems on Earth and represents the global sum of all ecosystems.

### Conclusion
The correct sequence of the ecological hierarchy is:
1. Individual Organism
2. Population
3. Community
4. Ecosystem
5. Biome
6. Biosphere

### Final Answer
The correct sequence representing the ecological hierarchy is:
**Individual Organism → Population → Community → Ecosystem → Biome → Biosphere**
