Photosynthesis produces oxygen and water. Photosynthesis is the result of a cycle. Humans use oxygen for respiration, the product produced from human respiration is carbon dioxide. Then plants absorb carbon dioxide from the air and turn it into oxygen with photosynthesis, this goes on and on as a cycle.
Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!
Well, Euglena is in phylum Euglenophyta, and Paramecium is in phylum Ciliophora. You can verify that with a quick Google search.

Both have an inverse relationship.
Explanation:
The two have an inverse relationship, that is, when elevation increases, atmospheric pressure decreases.
This is due to the amount of air on top of you at your current elevation.
At lower elevations, you have more air above you, and thus more pressure.
At higher elevations, you have less air above you, and thus less pressure.
At high elevation food takes longer time too cook due to low pressure, so at high altitude pressure cooker is used to cook food.
OK, :)
