Everything that breathes.
CO2 in the atmosphere is necessary for life to exist on Earth. Plants use Carbon Dioxide and give off oxygen to produce food in the process of photosynthesis. Plants and animals give off Carbon Dioxide as a waste product.
We would all die cause trees give us oxygen and carbon dioxide.
Green plants take in carbon dioxide during photosynthesis and give out oxygen. While respiration, all living organisms take in oxygen and carbon dioxide and then give out carbon dioxide.
They don't actually ID humans, they are looking for any living thing with blood. Those living things give off carbon dioxide and that is what the mosquito is looking for.
In the carbon dioxide-oxygen cycle, plants take in carbon dioxide during photosynthesis and release oxygen as a byproduct. Animals then consume this oxygen and release carbon dioxide as a waste product during respiration. This cycle maintains a balance of oxygen and carbon dioxide in the atmosphere essential for life on Earth.
Carbon Dioxide is exhaled by all living animals, even humans. The build up of Carbon Dioxide is poisonous but it's needed for this operation.Plant life, like trees, grass, flowers, etc., feed off of Carbon Dioxide, and they give off Oxygen. So what animals exhale, plants feed on and give us air in return.
Carbon dioxide, CO2
during photosynthesis plants take in carbon dioxide and give out oxygen
Carbon form carbon dioxide by oxydation.
Monkeys give off carbon dioxide when they exhale - the same as humans do!
A fox takes in oxygen and gives off carbon dioxide via the carbon dioxide cycle. All plants and animals are part of the carbon dioxide cycle. However, plants do things a little differently and take in carbon dioxide to use for photosynthesis. This results in plants giving off oxygen.
Cows release more carbon dioxide when they burp or release flatulence than a car does for a whole month....or something like that.
