The engines compress outside air in their compressors and some of this is tapped off at the right pressure to replace cabin air.

How will the level of carbon in the atmosphere change if humans do nothing to reduce their impact on the carbon cycle?
If humans continue doing nothing to reduce their impact on the carbon cycle then the levels of carbon dioxide in the atmosphere will continue to rise.
How does cellular respiration effect carbon and oxygen in the atmosphere?
Cellular respiration uses oxygen and generates carbon dioxide. Photosynthesis uses carbon dioxide and generates oxygen.
Would animals reduce co2 levels in the atmosphere?
No, only vegetation growing removes carbon dioxide from the atmosphere.
What are the most important steps developed countries could tke to help reduce levels of atomospheric carbon dioxide?
no
How can we reduce your carbon footprint?
If you want to reduce your carbon footprint, you can reduce your emissions of CO2 (carbon dioxide) into the atmosphere.
Cement work might reduce carbon dioxide why?
The cement work cannot reduce carbon dioxide. In fact, the cement work increases carbon dioxide because carbon dioxide is emitted during the production of cement.
How do carbon sinks reduce greenhouse gases?
A carbon sink is a storage for carbon. A tree is a carbon sink because it absorbs carbon dioxide (a greenhouse gas) from the atmosphere, stores the carbon and releases the oxygen. So forests are major carbon sinks which reduce the levels of greenhouse gas in the atmosphere.
Explain How a rain forest is able reduce carbon dioxide and produce oxygen?
A rainforest can reduce carbon-dioxide and produce oxygen by absorbing carbon-dioxide and releasing oxygen through photosynthesis.
Why is atmospheric carbon dioxide being measured?
Carbon dioxide is causing global warming and climate change. Countries are trying to reduce their emissions of this greenhouse gas. We measure CO2 levels to see if our preventative measures are having any effect.
Does an economical car reduce the amount of carbon dioxide in the air?
No car can actually reduce the amount of carbon dioxide in the air, but an economical car will add less additional carbon dioxide to the air than a less economical one.
How Can the internet reduce global warming?
Video conferencing can save people flying around the world to attend meetings. Flying planes releases carbon dioxide from fossil fuels.
How does the formation of sedimentary rocks reduce carbon dioxide levels?
Because sedimentary rocks are formed from tiny animals which have died and fallen to the sea bed millions of years ago. Due to more substances falling onto the sea bed above the animals, they are pressurized underground. Due to the heat of Earth's core, the animals are burnt under the ground, turning into fossil fuels.These animals contain carbon dioxide, and reduce the levels from the atmosphere by dying and travelling underground. This is how sedimentary rocks are a reason for reduced levels of carbon dioxide in the modern atmosphere.Other reasons are that the carbon dioxide dissolved into oceans which were formed millions of years ago. Also, the formation of plants reduced the carbon dioxide levels due to photosynthesis, as they intake it and do not replace it, as they produce oxygen and glucose as a result of photosynthesis.
