What happens to two species in mutualism?

Options

A. Only one is benefited
B. Both live differently
C. Both are benefited
D. Only one is harmed

Explanation

### Step-by-Step Text Solution:

1. **Definition of Mutualism**: Mutualism is a type of population interaction where two different species interact in a way that benefits both organisms involved.

2. **Characteristics of Mutualism**: In mutualism, both species provide resources or services that are essential for each other's survival and growth. This interaction is often described as a symbiotic association.

3. **Example of Mutualism**: A classic example of mutualism is the relationship between algae and fungi in lichens. In this association:
- **Algae's Role**: Algae perform photosynthesis and produce food (sugars) that nourish both themselves and the fungi.
- **Fungi's Role**: Fungi provide a protective environment and absorb water and minerals from the surroundings, which they share with the algae.

4. **Mutual Benefits**: In mutualism, both species benefit from the interaction. The algae gain a safe habitat and access to nutrients, while the fungi receive food produced by the algae.

5. **Conclusion**: Therefore, in mutualism, both species involved are benefited, which distinguishes it from other types of interactions where only one species benefits or one is harmed.

### Final Answer:
In mutualism, both species involved benefit from the interaction.
