Автор ответа: lili09051985

Объяснение:

Гумус образуется в почве в результате анаэробного преобразования растительных и животных органических остатков — гумификации. Процесс почвообразования, характеризующийся накоплением гумуса, называется гумусонакоплением, активное гумусообразование называется дерновым процессом
