The clear stratification is found in :-

Options

A. Tropical rain forest
B. Temperate deciduous forest
C. Grasslands
D. Deserts

Answer

**Step-by-Step Solution:**

1. **Understanding Stratification**: Stratification refers to the vertical distribution of different species in a community, where various species occupy different levels or layers.

2. **Identifying Ecosystems**: To determine where clear stratification is found, we need to consider different ecosystems. Common ecosystems include forests, grasslands, deserts, and aquatic systems.

3. **Analyzing the Forest Ecosystem**: Among these ecosystems, the forest ecosystem, particularly tropical rainforests, is known for its distinct stratification. In a tropical rainforest, there are multiple layers:
- **Herbs**: The lowest layer consists of herbaceous plants.
- **Shrubs**: Above the herbs, there are shrubs.
- **Medium-sized Trees**: Following the shrubs, we find medium-sized trees.
- **Tall Trees**: The uppermost layer consists of tall trees that form the canopy.

4. **Conclusion**: Given the clear stratification observed in the forest ecosystem, especially in tropical rainforests, the correct answer to the question is that clear stratification is found in the forest ecosystem.

**Final Answer**: The clear stratification is found in the forest ecosystem, particularly in tropical rainforests.
