Explanation:

Compost is a nutrient - rich organic matter. Its main use is to improve soil quality, which helps in growing plants and healing (restoring) the soil. "Food waste" is a component that can be used to make compost, not the reason for using compost. "To clean the earth" is not the primary purpose of compost; compost is focused on soil and plant - related benefits.

Answer:

to grow plants and heal soil
