When organisms interact with the various environmental factors, be it the abiotic components or the biotic components, there comes a time when adaptations begin to form, for the better survival of the race. Substantiate with the help of one example that in an ecosystem mutualists:
tend to co-evolve

Explanation

### Step-by-Step Text Solution:

1. **Understanding Mutualism**: Mutualism is a type of symbiotic relationship where both species involved benefit from the interaction. In ecosystems, mutualists often co-evolve, adapting to each other’s changes over time.

2. **Example of Co-evolution**: A classic example of mutualistic co-evolution is the relationship between the yucca plant and the yucca moth (specifically, the species Tegeticula).

3. **Role of the Yucca Moth**: The yucca moth plays a crucial role in the pollination of the yucca plant. When the female moth visits the yucca flower, she collects pollen from the flower’s anthers and then transfers it to the stigma of another yucca flower, facilitating cross-pollination.
