The rate of O2 production by the light reactions varies with the intensity of light because light is required as the energy sour
kupik [55]

Answer:

The correct answer is option a.

Explanation:

Yes, the light reactions also depend upon the Calvin cycle. Calvin cycle refers to a phenomenon that is used by the plants and algae to convert carbon dioxide from the atmosphere into sugar, the food needed by the autotrophs in order to grow. The plants rely upon the Calvin cycle for food and energy.  

In the given case, the rate of oxygen production would get diminish as the rate of ATP and NADP+ generated by the Calvin cycle diminishes. Of all the outcomes of the Calvin cycle, ADP and NADP+ are the only ones that get utilized by light reactions.  

The ADP and NADP+ are used up by the light reactions to fuel their reactions. This illustrates that if the rate of ADP and NADP+ generated by the Calvin cycle diminishes the production of oxygen by the light reactions also diminishes.

UV rays being harmful are blocked by the ozone layer in the stratosphere. Infrared rays that enter the earth’s atmosphere are trapped by the greenhouse gases like carbon dioxide, water vapour, methane etc. the trapped infrared rays help in providing warmth.
