The use of predator to control a pest is called

Options

A. Genetic engineering
B. biological control
C. Chemical control
D. Artifical control

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term used to describe the practice of using a predator to control a pest.

2. **Identifying the Options**: The options provided are:
- Genetic engineering
- Biological control
- Chemical control
- Artificial control

3. **Analyzing Each Option**:
- **Genetic Engineering**: This involves altering the genetic makeup of organisms using recombinant DNA technology. It is not related to pest control through predators.
- **Biological Control**: This method involves using living organisms, such as predators, parasites, or pathogens, to control pest populations. It is a natural way to manage pests.
- **Chemical Control**: This method uses synthetic chemicals to eliminate pests. It does not involve the use of predators.
- **Artificial Control**: This term is not commonly used in pest management and may refer to various non-natural methods, but it does not specifically denote the use of predators.

4. **Selecting the Correct Option**: Based on the analysis, the correct answer is **Biological Control**, as it specifically refers to the use of natural enemies like predators to manage pest populations.

5. **Conclusion**: The use of a predator to control a pest is called **Biological Control**.
