Options

A. food web
B. ecological pyramid
C. ecosystem
D. food chain

Explanation

To answer the question, "Organisms of a higher trophic level which feed on several types of organisms belonging to a lower trophic level constitute the," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Trophic Levels**:
- Trophic levels refer to the different levels in a food chain or food web. Organisms are categorized based on their feeding relationships.

2. **Identifying Higher Trophic Levels**:
- Higher trophic levels consist of organisms that are typically predators or carnivores. These organisms are fewer in number compared to those at lower trophic levels.

3. **Feeding Relationships**:
- Organisms at higher trophic levels often have a varied diet, meaning they can feed on multiple types of organisms from lower trophic levels. For example, a lion can eat deer, goats, and other animals.

4. **Examples of Trophic Levels**:
- In a simple food chain, plants (producers) are at the first trophic level, herbivores (like deer) are at the second, and carnivores (like lions) are at the third. The lion, as a higher trophic level organism, can consume various herbivores.

5. **Correct Terminology**:
- The question asks for a term that describes organisms at a higher trophic level that feed on several types of organisms. The correct term for this is a **"food web"**. A food web illustrates how various food chains are interconnected and shows the multiple feeding relationships among organisms.

6. **Conclusion**:
- Therefore, the answer to the question is that organisms of a higher trophic level which feed on several types of organisms belonging to a lower trophic level constitute the **Food Web**.

### Final Answer:
**Food Web**
