How do plants play a crucial role in the carbon cycle?

plant activity impacts the carbon cycle by introducing more carbon dioxide into the atmosphere: carbon dioxide accumulates in the atmosphere, changes temperatures and alters the salinity levels of oceans, disturbing the salt and water balance equilibrium that supports proper growth of marine plants and animals.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
