submit

Explanation:

Leftover food and leaf litter decompose. Decomposition is a natural process where organic matter is broken down by microorganisms. Through decomposition, these materials are transformed into nutrients - rich soil (humus). Banana peels and apple cores are part of the initial organic waste, not the end - product. Happy flowers are the result of using the rich soil (not the direct transformation of the waste).

Answer:

Rich soil
