It would depend on the person's size and how active they are. Find the CO2 rates for an hour during sleep and being awake, multiply them by whatever you need and you'll figure out an annual estimate. However, a rough estimate (curtesy of "The Earth Blog") assuming 12 breaths per minute (resting breath rate) is 500kg
The number is easy to estimate: breaths per minute x CO2 per breath x minutes per year
From Wiki - the breath rate is 12 to 25 per minute. Size of breath is 500 mL. Percent CO2 exhaled is 4% so CO2 per breath is approx 0.04g ( 2g/L x .04 x .5l).
CO2 Per year= 12 x 0.04 x 525600 (minutes per year) = 252kg/yr
CO2 (25 breaths) = 525 Kg/yr.
So - pick a number between 252 Kg/yr and 525Kg/yr
1000 lbs/year is a good figure of merit.
What else can I help you with?
Do humans inhale carbon dioxide?
Humans breathe in whatever happens to be in the air when they breathe in. If there is carbon dioxide then they will breathe it in as well as nitrogen and oxygen. However they only use the oxygen for respiration so they breathe out everything else with extra carbon dioxide.
Do humans exhale only carbon dioxide?
we also exhale water(h2o) along with carbon dioxide. All the constituents of the air we inhale are in the air we exhale. The proportions differ because of the gas exchange in the lungs.
What is the primary gas that humans exhale when breathing?
The primary gas that humans exhale when breathing is carbon dioxide.
Humans have greatly increased the level of what in the atmosphere?
Humans have greatly increased the level of carbon dioxide in the atmosphere. This is primarily due to the burning of fossil fuels for energy production, transportation, and industrial activities. This increase in carbon dioxide is a major contributor to global warming and climate change.
Humans have greatly increased the level of in the atmosphere.?
carbon dioxide
What is called the flow air into the lungs and out the lungs?
Oxygen is breathed in and carbon dioxide is breathed out as it is deadly to humans. Too much carbon dioxide breathed in will cause brain damage and eventually death.
Percentage of gases breathed out by humans?
The air we inhale is roughly 78% by volume nitrogen, 20% oxygen, 1% argon and 0.04% carbon dioxide, helium, water vapour, and small amounts of other gases.
Do humans inhale carbon dioxide?
Humans breathe in whatever happens to be in the air when they breathe in. If there is carbon dioxide then they will breathe it in as well as nitrogen and oxygen. However they only use the oxygen for respiration so they breathe out everything else with extra carbon dioxide.
What do humans exhale?
Human beings exhale carbon dioxide (CO2). We inhale a mixture that includes oxygen (O). It is the exact opposite process of that of plant life. This is why trees, forests and jungles are so important to the survival of all mammals (people and most animals).
How do mammoths breathe?
Mammoths are now extinct, but they were mammals just like we humans (unless you're not a human). They breathed in oxygen through their lungs and give out carbon dioxide.
How does carbon dioxide affects humans?
We exhale carbon dioxide or called CO2
Does carbon dioxide affect humans?
We exhale carbon dioxide or called CO2
What do humans breathe out and plants breathe in?
Carbon dioxide . It is part of the Carbon and Oxygen cycles. Humans ( all animals) breath in ( inhale) oxygen . It is used internally in the animated organism. It is then breathed out ( exhaled) as carbon dioxide. Carbon dioxide is a heavy gas, and 'falls' to the ground. Whereupon , it is absorbed by green plant life. Then under the process of photosynthesis within the plant , the carbon dioxide is broken down in to oxygen and carbon. The oxygen is released back into the atmosphere, and the carbon is kept in the plant as biomass.
What produes carbon dioxide?
Humans and animals produce carbon dioxide (CO2). They breath in oxygen, and in the mitochondria of cells, it creates carbon dioxide.
How do trees act as carbon sinks?
Trees act as carbon sinks by absorbing carbon dioxide from the atmosphere during photosynthesis and storing the carbon in their trunks, branches, leaves, and roots. This helps to reduce the amount of carbon dioxide in the atmosphere, which helps mitigate climate change by lowering greenhouse gas levels.
Which gas do humans breathe out?
carbon dioxide
Which gas do humans exhale?
Carbon dioxide
