The basic unit of study in ecology is:

Options

A. Population
B. Community
C. Organisms
D. Biome

Answer

**Step-by-Step Solution:**

1. **Understanding Ecology**: Begin by defining ecology. Ecology is the study of the relationships between organisms and their environment, including interactions with one another.

2. **Ecological Hierarchy**: Recognize that ecology operates within a hierarchical structure. This hierarchy includes several levels of organization:
- Atoms
- Molecules
- Cells
- Tissues
- Organs
- Organ systems
- Organisms
- Populations
- Communities
- Ecosystems
- Biomes
- Biosphere

3. **Identifying the Basic Unit**: From the hierarchy, identify the basic unit of study in ecology. The options provided are:
- Organism
- Population
- Community
- Biome

4. **Determining the Answer**: The basic unit of study in ecology is the organism. This is because an organism is the smallest unit that can carry out life processes and interact with its environment. Populations are made up of organisms, communities consist of multiple populations, and biomes encompass multiple ecosystems.

5. **Final Answer**: Therefore, the basic unit of study in ecology is **organism**.
