What is 'predation' ? Explain with the help of suitable examples why is it required in a community with rich biodiversity.

Explanation

**Step-by-Step Solution:**

1. **Definition of Predation**:
- Predation is an ecological interaction between two organisms where one organism, known as the predator, hunts and kills another organism, called the prey. This relationship is crucial in ecosystems as it helps regulate populations.

2. **Energy Transfer**:
- Predation plays a significant role in the transfer of energy within an ecosystem. It is a natural mechanism through which energy is transferred from lower trophic levels (prey) to higher trophic levels (predators). This energy flow is essential for maintaining the balance of the ecosystem.
