Ammount of oxygen consumed and carbon dioxide produced

• psyhprog
In summary, a person produces approximately 1 kg of carbon dioxide per day through breathing, but this does not contribute to an increase in atmospheric carbon dioxide levels as it is part of a closed loop. The amount of oxygen produced by plants varies among different species and can be estimated through experimental methods.

Is there anyway to find out or approximate how much carbon dioxide a person produces per day, how much oxygen does a plant produce per day. And do different species of plants produce different amounts of oxygen?

Not knowing offhand I just googled and the first thing that came up seems OK. http://100777.com/node/1278
If that is known there must obviously be experimental methods to determine it. Not hard to imagine methods to measure a person's current oxygen consumption.
Lots of ongoing research for more complicated things, sports medicine etc.
I have seen a calorimeter where they shut a person in for even 24h and measure that, heat production and lots of other stuff over the period.

The amount of carbon dioxide given off per human per day

Q. Should we be concerned with human breathing as a source of CO2?

A. No. While people do exhale carbon dioxide (the rate is approximately 1 kg per day, and it depends strongly on the person's activity level), this carbon dioxide includes carbon that was originally taken out of the carbon dioxide in the air by plants through photosynthesis - whether you eat the plants directly or animals that eat the plants. Thus, there is a closed loop, with no net addition to the atmosphere.

Amount of oxygen

And another estimate considers the percent of oxygen expelled back into the air along with the carbon dioxide.

1. How is the amount of oxygen consumed and carbon dioxide produced measured?

The amount of oxygen consumed and carbon dioxide produced can be measured using a device called a respirometer. This device measures the changes in gas volume as organisms respire, allowing for the calculation of the amount of oxygen consumed and carbon dioxide produced.

2. What factors affect the amount of oxygen consumed and carbon dioxide produced?

The amount of oxygen consumed and carbon dioxide produced can be affected by various factors such as the type of organism, its size and metabolism rate, as well as environmental factors such as temperature, humidity, and availability of nutrients.

3. Why is the amount of oxygen consumed and carbon dioxide produced important to study?

The amount of oxygen consumed and carbon dioxide produced is important to study as it provides valuable information about the metabolic processes of organisms. It can also give insight into the health and functioning of ecosystems, as well as the impact of human activities on the environment.

4. How does the amount of oxygen consumed and carbon dioxide produced relate to cellular respiration?

The amount of oxygen consumed and carbon dioxide produced is directly related to cellular respiration, which is the process by which cells convert oxygen and glucose into energy, carbon dioxide, and water. The more active a cell or organism is, the more oxygen it will consume and carbon dioxide it will produce through this process.

5. Can the amount of oxygen consumed and carbon dioxide produced be affected by external factors?

Yes, the amount of oxygen consumed and carbon dioxide produced can be affected by external factors such as temperature, humidity, and availability of nutrients. Changes in these factors can alter the metabolic rate of organisms, leading to changes in the amount of oxygen consumed and carbon dioxide produced.
