An athlete or a person with some disease may vary in dietary needs.
<h3><u>Explanation</u>:</h3>
The diet is one of the most important part of a human life. The person gets energy, all the macro and micro nutrients from the food. They get to have all protective principles of food from diet. There's an average balanced diet formula which says that the amount of carbohydrate to fat protein in a diet should be 3:1:1.
But it varies according to person's daily need of energy. For an athlete, the amount of energy needed is much more. So the amount of fat and protein in diet should increase. For an obese person, fat and carbohydrate restricted diet should be used. For a person with renal failure, very low protein diet should be suggested.
Explanation:
Carbon dioxide is needed for photosynthesis, but oxygen is needed for cellular respiration. Assuming there is still oxygen then the plants will produce carbon dioxide and some of it will be reabsorbed by photosynthesis during daylight. However, ultimately there wouldn’t be enough carbon dioxide for the plants to grow and they will start to die. Some plants have evolved a C4C4 photosynthesis pathway so they only require a small amount of CO2CO2 to survive, however they do still require more than zero CO2CO2.
So basically you killed off all the plants and all the other non-microbial life died of starvation shortly afterward.

Answer: They are both openings within the Earth but, Fumaroles release gases (carbon dioxide, sulfur dioxide, hydrogen chloride, and hydrogen sulfide) and steam, and Geysers release water and steam.
