How is oxygen available for both plants and human beings at night?

Human beings and plants absorb and expel different gasses from their systems as needed. In human beings, oxygen is important for the functioning of the cells. Oxygen is the fuel our body cells use to convert the food we eat into energy. During the energy generation process, carbon dioxide is produced as waste, and the body gets rid of it through respiration. Thus, during respiration, human beings take in oxygen and remove carbon dioxide based on the body's requirements.


During photosynthesis, which occurs during the day, plants use light energy, carbon dioxide, and water to produce food/ energy. Oxygen is also produced and released as waste. In the dark, plants take in oxygen for respiration and expel carbon dioxide.


At night, both plants and human beings use up oxygen, as it is available for both organisms. Plants and human beings do not utilize the net available atmospheric oxygen. In addition, the current number of organisms is incapable of using all the atmospheric oxygen available. Competition for oxygen between the two would only occur in an air-tight or poorly ventilated room with inadequate or no access to atmospheric air.

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

A man has a garden measuring 84 meters by 56 meters. He divides it into the minimum number of square plots. What is the length of the square plots?

We wish to divide this man's garden into the minimum number of square plots possible. A square has all four sides with the same length.Our garden is a rectangle, so the answer is clearly not 1 square plot. If we choose the wrong length for our squares, we may end up with missing holes or we may not be able to fit our squares inside the garden. So we have 84 meters in one direction and 56 meters in the other direction. When we start dividing the garden in square plots, we are "filling" those lengths in their respective directions. At each direction, there must be an integer number of squares (otherwise, we get holes or we leave the garden), so that all the square plots fill up the garden nicely. Thus, our job here is to find the greatest common divisor of 84 and 56. For this, we prime factor both of them: `56 = 2*2*2*7` `84 = 2*2*3*7` We can see that the prime factors and multiplicities in common are `2*2*7 = 28` . This is the desired length of the square plots. If you wi...
