Which of the following is formed by interlinking of different food chains?

Options

A. Ecosystem
B. Food chain
C. Food web
D. Trophic level

Answer

To solve the question "Which of the following is formed by interlinking of different food chains?", we can follow these steps:

### Step 1: Understand the Terms
First, let's clarify the terms given in the options:
- **Ecosystem**: A biological community of interacting organisms and their physical environment.
- **Food Chain**: A linear sequence of organisms through which nutrients and energy pass as one organism eats another.
- **Food Web**: A complex network of feeding relationships (interconnected food chains) among various organisms in an ecosystem.
- **Trophic Level**: The position an organism occupies in a food chain, which can be primary producers, primary consumers, secondary consumers, etc.

### Step 2: Analyze the Question
The question asks about the formation that occurs when different food chains are interconnected. This implies that we are looking for a structure that represents multiple feeding relationships.

### Step 3: Evaluate Each Option
- **Ecosystem**: While ecosystems contain food chains, they are not formed solely by interlinking food chains.
- **Food Chain**: This is a singular pathway of energy flow and does not represent interlinking.
- **Food Web**: This is the correct answer because it is specifically defined as a network of interconnected food chains.
- **Trophic Level**: This refers to the levels in a food chain and does not represent the interlinking of food chains.

### Step 4: Conclusion
Based on the analysis, the correct answer is **Food Web**. A food web is formed by the interlinking of different food chains, showcasing how various organisms are interconnected through feeding relationships.

### Final Answer
The correct answer is **Food Web**.
