What is trophic level ?

Explanation

**Step-by-Step Solution:**

1. **Definition of Trophic Level**: A trophic level is defined as a group of organisms that share the same position in a food chain or food web. This means that these organisms obtain their energy from the same source.

2. **Energy Consumption**: Organisms at the same trophic level consume energy from the same type of organism. For example, if we have a food chain consisting of organisms A, B, C, and D, all organisms at the same level (e.g., B) will feed on the same type of organism (A).

3. **Food Chain Example**: In a food chain, each level represents a different trophic level. For instance, if A is a producer (like a plant), then B (a herbivore) feeds on A and is at the second trophic level. C (a carnivore) that feeds on B would be at the third trophic level, and so on.
