Which type of association is found in between entomophilous flower and pollinating agent ?

Options

A. mutualism
B. Commensalism
C. Cooperation
D. Co-evolution

Explanation

### Step-by-Step Solution:

1. **Identify the Key Terms**: The question refers to "entomophilous flowers" and "pollinating agents." Entomophilous flowers are those that are pollinated by insects.

2. **Understand the Interaction**: In this relationship, insects visit these flowers primarily for food sources such as nectar or pollen. While the insects benefit by obtaining food, they also facilitate the pollination process for the flowers.

3. **Define the Type of Association**: The interaction between entomophilous flowers and their pollinators is a type of association where both parties benefit. The flowers get pollinated, which is essential for their reproduction, while the insects receive nourishment.

4. **Classify the Relationship**: This type of interaction is classified as **mutualism**. In mutualism, both organisms involved gain benefits from the relationship, making it a mutually beneficial association.

5. **Eliminate Other Options**:
- **Commensalism**: One organism benefits while the other is neither helped nor harmed. This does not apply here.
- **Cooperation**: While both organisms benefit, they are not dependent on each other for survival, which is not the case with entomophilous flowers and their pollinators.
- **Co-evolution**: This refers to the adaptations that occur in both species over time, but it does not specifically define the type of association.

6. **Conclusion**: Therefore, the correct answer to the question is that the association between entomophilous flowers and their pollinating agents is an example of **mutualism**.
