No, it just means your oxygen requirement is not high enough for your brain to activate the breathing mechanism to go faster or deeper. You can overcome this consciously by breathing faster and deeper, but this would cause you to hyperventilate and pass out.
False - If you are exercising, you are breathing more.
It takes approximately 3 seconds to breathe in and 3 seconds to breath out for regular breathing. It will be less time the faster your respiration rate is.
No because they still have to breathe like others do to.
B/c the higher you go the less air there is to breathe from.
It's healthy to be a deep breather, with a short while daily doing breathing exercises, and when you consciously make certain your diaphram, just a bit lower than the stomach, is the part to breath in and out, for awhile daily, and to at the same time, breath in for 10 seconds and then out for 10 seconds, even with the palm of the hand just below the waist, to then do this breathing, if this is done daily, then the breathing will become deeper at all times. Shallow breathing means there's less oxygen in the body and the brain, so the deeper breathers can be smarter and healthier. Naturally, oxygen from the air and mother nature, are converted into better intelligence ratios or I.Q.; plus other healthier ways.
You can breathe with a hole in your pleural sac if the hole remains small. The hole will make breathing less efficient and air will escape from the pleural lining into other parts of they body, but one can breathe.
Dead animals don't breathe
Yes. Because you are breathing in less nitrogen therefore less nitrogen can be dissolved into your blood. I think the average is 34% oxygen (Compared to the normal 21%) however 100% burns your lungs.
Pressurization is for the comfort of crew and passengers. The planes fly higher to save on fuel. The less dense air higher up causes less drag. It is also unfortunately harder to breathe. Pressuriziation makes it easier to breathe without special equipment, like breathing apparatus or oxygen.
Deep breathing lays the groundwork for good health. When you breathe deeply, you are less stressed, which prevents many illnesses. Plus, deep breathing promotes calmness, so you are less irritated and anxious, which also helps prevent chronic health conditions. I try to practice deep breathing techniques a few times each day, particularly in the morning and evenings.

The breathing rate of aquatic animals is faster than that of terrestrial animals because the amount of dissolved oxygen in the water in much less than the amount outside, so they have to breathe more in order to get more oxygen
Less, because humus is composed of organic material that's at it's break down point, so the deeper you dig the less organic materials there is
