Explanation:

Predation refers to the interaction between two organisms in which one organism (predator) hunts, captures, and feeds on another organism (prey). It is a common ecological interaction that plays a crucial role in the balance of ecosystems.

Example of Predation:

The correct answer is option 'B' - Biological control of pest population.

Biological Control of Pest Population:

Biological control is a method used to manage and control pest populations by introducing natural predators or parasites that feed on the pests. This is done to reduce the damage caused by pests without the use of chemical pesticides. It is an environmentally friendly approach that aims to maintain a balance in nature.

Explanation of the Example:

In this example, the predator is the natural enemy introduced to control the pest population, and the prey is the pest population itself. Let's take an example of aphids, which are small insects that feed on plants and cause damage to crops. Ladybugs are natural predators of aphids and feed on them.

1. Predator: Ladybug (natural enemy)
2. Prey: Aphids (pest population)

When ladybugs are introduced into an area infested with aphids, they actively hunt, capture, and feed on the aphids. This feeding behavior of ladybugs on aphids is an example of predation.

Significance of Biological Control:

Biological control of pest populations has several advantages over the use of chemical pesticides:

1. Environmentally friendly: Biological control does not involve the use of harmful chemicals, reducing the negative impact on the environment.
2. Targeted approach: Natural predators are specific to particular pests, ensuring that only the intended pest population is controlled.
3. Long-term solution: Biological control can establish a sustainable balance in nature by reducing pest populations over an extended period.
4. Cost-effective: Once natural predators are established, they can reproduce and maintain their populations without the need for continuous intervention.

Overall, biological control of pest populations through the introduction of natural predators is an effective example of predation that helps in managing pest populations and maintaining ecological balance.
