Answer to Question #104782 in Biology for Azariah B Cutchall

Question

If you hear that a community is experiencing light pollution, you would be concerned about the plants because:
Question 1 options:

herbivory will increase,


photosynthesis will speed up,


the photoperiod will be disrupted,


an excess of daylight will deplete their energy

Answer 1

The photoperiod will be disrupted.

Light pollution is characterized by the excessive intensity of artificial light during night periods. Many processes that occur in plants significantly depend on circadian rhythms associated with the alternation of daytime and night. These changes are detected by plants and regulate its growth, metabolism, development of organs (i.e., flowers), interaction with pollinating animals, etc. Disrupted photoperiods caused by light pollutions may significantly impair physiological processes in plants.
