Why is CO2 necessary for our environment?

Question

Why is CO2 necessary for our environment?

Answer 1

Trees use carbon dioxide during photosynthesis to make glucose and starch which they can use in respiration or other cellular processes.

In humans carbon dioxide (in the form of bicarbonate and carbonic acid) is used as a buffer to regulate the pH of our blood.

Answer 2

it's necissary for plant respiration, which in turn give off oxygen..

animals are dependant on plant lif t flourish..

but plants would survive with or without animal life

trees actually play a rather insignificant role in oxygenation of the atmosphere.. not to say they aren't important for thus and other reasons.. but algea in the oceans oxygenates most of the air..

Answer 3

Because it's essential for trees to have.

The trees take in the CO2 and exahle oxygen which is necessary for us.

So basically if we build more trees then:

Less Pollution, More Oxygen

Better World :D

Best of Luck!

Answer 4

plants uses co2 for photosynthsis take a look at formula

6co2+6h2o makes c6h12o6+6o2

plants uses co2(corbon) and make o2(oxygen) for humans.

plants uses o2 at night because they only need corbon for photosynthesis
