The interlinking of various food chains in an ecosystem is known as ________

Explanation

**Step-by-Step Solution:**

1. **Understanding Food Chains**: A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem. It typically starts with a producer (like plants) and moves up to various levels of consumers (herbivores, carnivores, etc.).

2. **Interlinking of Food Chains**: In an ecosystem, multiple food chains exist simultaneously. These chains do not operate in isolation; they are interconnected. This interconnection allows for a more complex representation of how energy and nutrients circulate within the ecosystem.

3. **Definition of Food Web**: The term used to describe the interlinking of various food chains in an ecosystem is "food web." A food web illustrates the complex feeding relationships among organisms, showing how different food chains overlap and interact.
