Which photosynthetic process will be lest affected by shorter periods of daylight? a. the reaction at photosystem 1b. the formation of atpc. the calvin cycled. the reaction at photosystem 2

The correct option would be option C. The Calvin cycle.

Explanation:

The Calvin cycle is the set of chemical reactions that use chemical energy to produce glucose molecule and a 5 carbon molecule called RuBP. It takes place in the chloroplast of the cell.

The Calvin cycle also called as dark reaction or light-independent reaction because it takes place after the energy captured from the sunlight. The Calvin cycle does not directly depend on the light or photoperiodism (shorter or longer periods of daylight) so it will be least affected by a shorter period of daylight.

Thus, the correct option is C.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
