A fibrous roots system is efficient in
(a) Food Storage
(b) Nitrogen fixation
(c) Good anchorage
(d) Absorption for deep soil layers

Options

A. Food Storage
B. Nitrogen fixation
C. Good anchorage
D. Absorption for deep sail layers.

Answer

To solve the question regarding the efficiency of a fibrous root system, we need to analyze each option provided:

1. **Understanding Fibrous Root System**: A fibrous root system consists of numerous thin roots that spread out in various directions from the base of the plant. This structure is different from a taproot system, which has one main root.

2. **Analyzing the Options**:
- **(a) Food Storage**: Fibrous roots are not primarily designed for storing food. They are more focused on absorption and anchorage.
- **(b) Nitrogen Fixation**: While some plants can fix nitrogen, fibrous roots themselves do not play a significant role in this process. Nitrogen fixation is more commonly associated with specific plants like legumes that have specialized root nodules.
- **(c) Good Anchorage**: Fibrous roots are very effective at anchoring the plant in the soil due to their extensive network. This allows the plant to remain stable and upright, especially in windy conditions.
- **(d) Absorption for Deep Soil Layers**: Fibrous roots generally do not penetrate deeply into the soil. Instead, they are more effective at absorbing moisture and nutrients from the upper layers of soil.

3. **Conclusion**: Based on the analysis, the option that best describes the efficiency of a fibrous root system is **(c) Good anchorage**. This is because the diverse and widespread nature of fibrous roots provides excellent stability for the plant.

### Step-by-Step Solution:
1. Identify the characteristics of a fibrous root system.
2. Evaluate each option based on the role of fibrous roots.
3. Determine that the fibrous root system is not primarily for food storage or nitrogen fixation.
4. Conclude that the main efficiency of a fibrous root system is in providing good anchorage.
