In which ecosystem species diversity is low ?

Options

A. Tundras
B. Deciduous forests
C. Deserts
D. Grasslands

Answer

To determine in which ecosystem species diversity is low, we can analyze the given options: tundras, deciduous forests, deserts, and grasslands.

### Step-by-Step Solution:

1. **Understanding Species Diversity**:
- Species diversity refers to the variety of different species within a particular ecosystem. Higher diversity typically indicates a more complex and stable ecosystem.

2. **Analyzing the Ecosystems**:
- **Tundras**: Characterized by extremely low temperatures, especially in winter. The harsh climate limits the types of plants and animals that can survive there. Typically, only a few species of grasses, mosses, and shrubs can thrive, leading to low species diversity.
- **Deciduous Forests**: These forests experience four distinct seasons and have a variety of trees and plants. They support a wide range of species, resulting in high species diversity.
- **Deserts**: Although deserts have extreme conditions, they can support a variety of specially adapted plants and animals. The species diversity here is moderate, not low.
- **Grasslands**: These ecosystems are dominated by grasses and can support various herbivores and predators. They also have moderate species diversity.

3. **Conclusion**:
- Based on the analysis, the tundra ecosystem is the one with low species diversity due to its extreme climate conditions that limit the types of organisms that can survive there.

### Final Answer:
The ecosystem in which species diversity is low is the **Tundra**.
