A food web

Options

A. Increases the variety of food at each trophic level
B. Delicately balances the inter-relations amongst organisms
C. Decreases the variety of food but increases the quantity of food at each trophic level
D. Increases the variety as well as the quantity of food at each trophic level

Answer

### Step-by-Step Solution:

1. **Understanding Food Web**: A food web is defined as a network of interconnected food chains. It represents the feeding relationships among various organisms in an ecosystem.

2. **Components of a Food Web**: A food web consists of producers (like plants), consumers (herbivores and carnivores), and decomposers (like bacteria and fungi). Each of these components plays a crucial role in the ecosystem.

3. **Function of a Food Web**: The primary function of a food web is to maintain the balance among different organisms. It ensures that energy and nutrients are transferred through various trophic levels, supporting a diverse range of life.

4. **Analyzing the Options**:
- **Option 1**: Increases the variety of food at each trophic level. (Not entirely accurate as it focuses only on variety)
- **Option 2**: Delicately balances the interrelations among the organisms. (Correct, as it emphasizes the balance maintained by the food web)
- **Option 3**: Decreases the variety of food but increases the quantity of food at each trophic level. (Incorrect, as it misrepresents the function of a food web)
- **Option 4**: Increases the variety as well as the quantity of food at each trophic level. (Partially true but does not capture the essence of balance)

5. **Conclusion**: Based on the analysis, the correct answer is **Option 2**: "Delicately balances the interrelations among the organisms."
