Ho do plants help us to breathe?

Question

Ho do plants help us to breathe?

Answer 1

they give oxygen

Answer 2

They take in CO2 and give us back O2. The plants need CO2 as much as u need O2.

Answer 3

As animals inhale Oxygen, their bodies exhale CO2.

Plants "inhale" CO2 and exhale oxygen. This is one of the basic life cycles.

Multiple studies have shown that plants thrive in a higher CO2 environment.

Answer 4

plants absorb the carbon monoixide that we exhale and in return the trees let off oxygen

Answer 5

They don’t actually help us breathe, but they provide oxygen for us to breathe. In short, plants absorb carbon dioxide (CO2) from the air, and through the photosynthetic process convert it into sugars that feed the plant and then they release excess oxygen back into the air.

Answer 6

Trees and plants produce oxygen and in return take the carbon dioxide out of the air for us. This is why deforestation is so bad (for the trees, us and earth!)

Answer 7

They help us because we exhale carbon dioxide and breath oxygen. Plants are just the opposite, they breath carbon dioxide and expel oxygen so its a parnership that neither one can live without.

Answer 8

yes, they are the ones who produce oxygen for us

Answer 9

Plants absorb carbon DIOXIDE, use the carbon for growth and release the oxygen. Reduce the carbon dioxide in the atmosphere and kill the plants and that would kill us.

Answer 10

Trees breathe in what we breath out. Us humans breathe out carbon dioxide and breathe in oxygen. Trees breathe out oxygen and breathe in carbon dioxide, Trees and plants also help by keeping the air clean and free of toxins.

Answer 11

it just helps
