Question

what type of tree gives off lots of oxygen and is easy to grow north america?

Answer 1

all plants give off lots of oxygen.  they take in the pollutants carbon monoxide and clean the air.

Answer 2

a big one??? I would say the bigger the tree the more photosynthesis that occurs and the more oxygen is produced! Its a vague question ( ie not scientifically posed) so you could take it as saying the largest amount of oxygen produced as say an amount, the largest amount of oxygen produced for the size of the tree, that producs the largest quantity of oxygen per anum ( ie is evergreen) etc

Something with large leaves maybe or something that is evergreen...the giant sequoia is big, but I don't know if it has high photosynthtic rates....or if its easy to grow ( I think it pretty isolated in where it grows)
