The activity of Earth's biosphere
air
Plants reduce the amount of carbon dioxide in the air and increase the amount of oxygen.
Trees perform photosynthesis and so they PRODUCE OXYGEN. All creatures need oxygen in the air to breathe, so trees make the air breathable.
Plants, which are on the first trophic level, can also be referred to as producers or autotrophs.
During expiration, the air in the lungs has already been used for gas exchange in the alveoli, leading to a decrease in oxygen and an increase in carbon dioxide levels. This results in the drop in the amount of oxygen between inspired and expired air.
To find the amount of oxygen used, we need to consider the difference in mass between sodium and sodium oxide. The mass increase is 16g (62g - 46g) which corresponds to the amount of oxygen used from the air. Therefore, 16g of oxygen from the air were used.
Gasping for air typically happens when your body is trying to get more oxygen. It could be a response to a sudden shock, physical exertion, or a medical issue like asthma or heart problems. Gasping can help increase the amount of oxygen you're taking in to meet the body's increased demand.
Cutting down trees does increase the amount of carbon dioxide in the air because trees take the carbon monoxide in the air and turn it into oxygen in a process called photosynthesis. Without as many trees then there is going to be more carbon dioxide in the air.
To increase the amount of oxygen that will dissolve in 100 grams of water, you can lower the temperature of the water, as colder temperatures allow more gas to dissolve. Additionally, increasing the pressure above the water can enhance the solubility of oxygen due to Henry's law. Stirring or agitating the water can also help to increase oxygen dissolution by promoting contact between the water and oxygen in the air.
Photosynthesis is called an air purifying process because plants take in carbon dioxide from the air during photosynthesis and release oxygen as a byproduct. This helps to reduce the amount of carbon dioxide in the atmosphere and increase the level of oxygen, which benefits both plants and animals by improving air quality.
Air is 20.5 percent oxygen.
The amount of carbon dioxide in the atmosphere increases primarily through processes such as combustion, respiration, and deforestation. During cellular respiration, organisms convert glucose and oxygen into energy, producing carbon dioxide as a byproduct. Simultaneously, the amount of oxygen in the air decreases during respiration and combustion, as oxygen is consumed in these processes. Additionally, deforestation reduces the number of trees that produce oxygen through photosynthesis, further contributing to the decrease in atmospheric oxygen levels.
