Answer: D
Explanation: Oxygen plays a vital role in energy production via a system called electron transport chain , which is an important component of cellular respiration. ... Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production
During exercise, a number of changes occur to maximise the body's oxygen intake. Firstly our heart rate/ pulse increases. This is due to the heart beating much faster and more forcefully to pump blood faster around the body.
Our breathing rate increases to intake more oxygen and exhale more CO2.
The smooth muscle in our trachea and bronchi relaxes to increase the lumen size thus making breathing easier. Adrenaline may also be released leading further amplifying these changes as well as reducing blood flow to the gut and thus peristalsis occurs at a much slower rate.
Also when we exercise we respire more, producing heat, which must be expelled. This may be done through sweating. Another physiological change that occurs is vasodilation of arterioles closer to the skin to allow more blood to flow closer to the skin, allowing more heat to radiate out.

Answer:
The correct option is DECREASED LEVELS OF CARBON DIOXIDE.
Explanation:
The major factors affecting photosynthesis rate are light intensity, carbon dioxide concentration and temperature. Increase or decrease in any of these three factors will directly affect the rate at which photosynthesis takes place. Increase concentration of carbon dioxide will generally increase photosynthesis while a decrease in its concentration will reduce the rate at which photosynthesis takes place.
