Monika was observing a lizard on the wall which chased an insect and ate it. She felt that lizard is cruel and ugly. Suddenly the lizard fell and was eaten by a cat. She started thinking, how organisms are connected to each other for their food? What is a food chain? Will the world be a better place without lizards?
Make a food chain of five organisms.
To which trophic level does the lizard belong

Explanation

### Step-by-Step Solution:

1. **Understanding the Observation**: Monika observed a lizard chasing and eating an insect. This indicates a predator-prey relationship, where the lizard is the predator and the insect is the prey.

2. **Defining a Food Chain**: A food chain is a sequence that shows how energy and nutrients flow from one organism to another in an ecosystem. It illustrates who eats whom, starting from producers (like plants) to various levels of consumers.

3. **Creating a Food Chain**: To create a food chain, we can select five organisms that represent different trophic levels. Here’s an example:
- **Grass (Producer)**: The first level consists of producers, which are usually plants that produce energy through photosynthesis.
