Ecology is basically concerned with the following levels of organization

Options

A. 1)Organisms
B. 2)Population and communities
C. 3)Biomes
D. 4)All

Answer

**Step-by-Step Solution:**

1. **Understanding Ecology**: Begin by defining ecology as a branch of biology that studies the interactions between living organisms and their physical environment. This includes both biotic (living) and abiotic (non-living) factors.

2. **Identifying Levels of Organization**: Recognize that ecology is concerned with different levels of organization. These levels help in understanding how organisms interact with each other and their environment.

3. **List the Levels of Organization**:
- **Organism**: The smallest unit of organization, representing individual living entities.
- **Population**: A group of organisms of the same species living in a specific area.
- **Community**: An assemblage of different populations that live together in a defined area.
- **Biome**: The largest level of organization, which consists of several communities that share similar climate and environmental conditions.

4. **Analyzing the Options**: Review the provided options in the question to see which levels of organization are mentioned. The options include:
- Organism
- Population
- Community
- Biomes

5. **Selecting the Correct Answer**: Since all four levels (organism, population, community, and biome) are fundamental to the study of ecology, the correct answer would be the option that includes all these levels.

6. **Conclusion**: Therefore, the answer to the question is that ecology is concerned with all four levels of organization.

**Final Answer**: Ecology is basically concerned with the levels of organization: organism, population, community, and biome.
