The term 'fall ecosystem' is primarily used in North American environmental science and education, particularly in regions where autumn is pronounced (northeastern USA and Canada). In Brazil, due to tropical and subtropical climate, this concept is less emphasized in everyday language, though it is understood and used in scientific contexts. The fall ecosystem is culturally significant in the USA and Canada as it represents a critical period for wildlife preparation and is often studied in schools during autumn months.
