Fotoperiodiek
Fotoperiodiek is a phenomenon in plants and animals related to the duration of daylight or darkness in a 24-hour cycle. This response to light is crucial for regulating various biological processes, including flowering in plants, migration and reproduction in animals, and sleep-wake cycles.
In plants, photoperiodism determines when they will flower. Short-day plants flower when the days are short
In animals, photoperiodism influences seasonal behaviors. For instance, many birds migrate and breed during specific seasons
