Startification is useful in

Options

A. Better use of resources
B. Accommodation of larger number of species
C. Modification of environment
D. All the above

Answer

**Step-by-Step Text Solution:**

1. **Understanding Stratification**:
- Stratification refers to the vertical distribution of different species within an ecosystem. This means that various species occupy different levels or layers in a habitat, such as trees, shrubs, and ground cover in a forest.

2. **Better Use of Resources**:
- One of the key benefits of stratification is that it allows for better utilization of resources. Since different species occupy different levels, they can exploit different resources (like sunlight, water, and nutrients) without competing with each other. This reduces competition and enhances resource use efficiency.

3. **Accommodation of Larger Number of Species**:
- Stratification also promotes biodiversity. By allowing different species to occupy different layers, more species can coexist in the same ecosystem. For instance, some species may thrive in the canopy while others may prefer the understory or forest floor.

4. **Modification of Environment**:
- Additionally, stratification can lead to environmental modifications. Species at different levels can interact and influence their surroundings. For example, the presence of taller trees can create shade for smaller plants, and the fallen leaves from the upper layers can enrich the soil below.

5. **Conclusion**:
- Therefore, stratification is useful for all the reasons mentioned: better use of resources, accommodation of a larger number of species, and modification of the environment. Thus, the correct answer is "all of the above."
