The day and night is provided us due to the rotation of earth at its own axis.
Answer2:
The equal day and night is the result of the Equinox, where the declination of the sun rises due east and sets due west. The sun's declination is zero.

∙ 13y agoThere is no place on earth where the relative lengths of day and night don't change
through the year.
Our guess is that you're thinking of the Equator. The equator is the line on which the
variations in day/night during the year are the smallest; but they still change, even on
the equator.
Here's what happens on the equator:
March 21: Day/night equal. 12 hours / 12 hours
March 21 - June 21: Day shrinking, night growing.
June 21 - September 21: Day growing, night shrinking
September 21: Day/night equal. 12 hours / 12 hours
September 21 - December 21: Day shrinking, night growing.
December 21 - March 21: Day growing, night shrinking.

How does critical night length control photoperiodism?
Photoperiodism is the response of the plant to daylight and darkness. For short day plants it will bloom in darkness and when darkness exceeds critical night length, for long day plants it will bloom during daylight and when darkness is less than the critical night length.
