Question

the plants shown bloom in summer. which statement explains why the plants bloom in summer? the nights are shorter. the nights are longer. the nights are colder. the nights are warmer.

Explanation:

Plants that bloom in summer are often short - day plants. However, summer has longer days and shorter nights. Some plants respond to the shorter night length (longer day length) as a cue to bloom. Warmer nights (\( \text{The nights are warmer} \)) are not the main cue for blooming in most cases. Colder nights (\( \text{The nights are colder} \)) are more associated with fall or winter. Longer nights (\( \text{The nights are longer} \)) are more typical of fall.

Answer:

The nights are shorter.
