Final answer:
The demand for annuals for flower beds during spring is most likely influenced by 1)seasonality, which refers to the cyclical pattern of changes that occur in nature. Plants have biological responses to the timing and duration of day and night, known as photoperiodism, which controls flowering and other growth processes. Day length is an important indicator of the time of year for plants.
Step-by-step explanation:
The demand for annuals for flower beds during spring is most likely influenced by 1)seasonality.
Seasonality refers to the cyclical pattern of changes that occur in nature, such as the change of seasons. Plants have biological responses to the timing and duration of day and night, known as photoperiodism. This controls flowering and other growth processes. Day length is an important indicator of the time of year for plants.
