Which of the following represents diversity at ecosystem at ecosystem level?

Options

A. Genetic diversity
B. Ecological diversity
C. Species diversity
D. Species evenness

Answer

To determine which option represents diversity at the ecosystem level, we need to analyze the provided options in relation to the concept of biodiversity. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Biodiversity**:
- Biodiversity refers to the variety of life forms within a given ecosystem, biome, or on the entire planet. It encompasses diversity at multiple levels, including genetic, species, and ecological levels.

2. **Identifying the Levels of Diversity**:
- **Genetic Diversity**: This refers to the variation in genetic makeup among individuals within a species. It is important for the adaptability and survival of species but does not represent ecosystem diversity.
- **Species Diversity**: This refers to the variety of species within a particular ecosystem or area. While it is a crucial aspect of biodiversity, it does not encompass the broader ecosystem level.
- **Ecological Diversity**: This refers to the variety of ecosystems within a certain area, including the different habitats, communities, and ecological processes. This is the level that specifically addresses diversity at the ecosystem level.
- **Species Evenness**: This term describes how evenly the individuals are distributed among the different species in a community. While it is related to species diversity, it does not represent ecosystem diversity.

3. **Selecting the Correct Option**:
- Based on the definitions, **Ecological Diversity** is the option that represents diversity at the ecosystem level. It encompasses the variety of ecosystems and their interactions, making it the correct answer to the question.

### Final Answer:
The correct option that represents diversity at the ecosystem level is **Ecological Diversity**.
