• C. Chemical
• D. Enzymatic

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The question asks for the term that describes a pest management strategy based on using living organisms.
Step 2: Detailed Explanation:
Pest control methods can be broadly categorized:
Physical Control: Using barriers, traps, heat, or manual removal to manage pests.
Biological Control (Biocontrol): Using other living organisms, such as predators, parasitoids, or pathogens, to suppress a pest population. The use of a natural predator fits this definition perfectly. For example, using ladybugs to control aphids.
Chemical Control: Using synthetic pesticides or chemicals to kill pests.
Enzymatic Control: This is not a standard category of pest control. It would imply using specific enzymes, which is not what is described.
Step 3: Final Answer:
The use of natural predators to control pathogens or pests is the definition of biological control.
