Here are a few options depending on the age and context:
For younger kids (preschool-early elementary):
* "The garden is fertile, so the flowers grow big and strong!" (Focus on the result of being fertile - good growth)
* "The soil in the garden is fertile, like good food for the plants." (Focus on the concept of nourishment)
For slightly older kids (elementary):
* "The farm is fertile because it has lots of good soil for the crops to grow in." (Focus on agricultural context)
* "The farmer uses special techniques to make the land fertile so they can grow lots of food." (Focus on human effort and impact)
Remember, it's important to use language that is age-appropriate and avoids any potentially sensitive or confusing topics.
