Scientists often classify organisms based on their ability to perform certain processes
Mrac [35]

A. Plants can make their own food using energy from the Sun.

Animals cannot make their own food.

Explanation:

An example of the physiological capabilities of plants is their ability to make food on their own using the energy from the sun and chemical substances in the environment, animals do not make their own food.

  • Physicological ability refers the body functions of an organism. It refers to the life biochemical processes a body is able to carry out based on its design.
  • Metabolism is a living function attributable to all life.
  • Organisms can either build up energy such as seen in plants during photosynthesis. This process is called anabolism.
  • Some other organisms, makes use of the energy in their own life process and this is a catabolic process.

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.
