Among the ecosystem services are control of floods and soil erosion. How is this achieved by the biotic components of the ecosystem?

Explanation

**Step-by-Step Solution:**

1. **Understanding Biotic Components**: The biotic components of an ecosystem refer to all the living organisms, including plants, animals, and microorganisms. In this context, we will focus on how plants contribute to controlling floods and soil erosion.

2. **Role of Plant Roots**: Roots of plants play a crucial role in preventing soil erosion. They anchor the soil in place, which helps to keep it from being washed away by rain or flowing water. This anchoring effect is vital for maintaining soil structure and stability.

3. **Soil Porosity**: Roots also contribute to making the soil more porous. When roots grow, they create channels in the soil, which increases its porosity. This porosity allows water to infiltrate the soil rather than running off the surface, which helps to reduce the risk of flooding.
