how do we benefit from plants? they say they take Co2 from the air but they do the opposite at night??

Question

i know we benefit from plants, but i mean among gas

Answer 1

Like animals, plants have to respire to release energy all day long, not just at night. But during the day, they carry out photosynthesis, which produces far more O2 than they need. Their need for O2 is low, because they do not have to move around. They are net O2 producers, and so all animals benefit.

Answer 2

First and foremost, plants capture energy from the sun and convert it to a form that can be used by animals. We cannot use the sun's energy directly as fuel. We eat plants and animals as a source of energy to live. Yes, plantss do release CO2 at night, but why is that a problem? It doesn't produce anywhere near the amount that an animal of comparable mass produces.

Answer 3

We benefit from plants because they give us our O2! In photosynthesis, O2 is a waste product! But for us, in cellular respiration, it's needed!

But remember that plants do cellular respiration in their own mitochondria, just like us.

Answer 4

oh god no..... they just keep sucking in C02 to produce their energy through photosynthesis, but they do release the C02 back to the atmosphere after they die and are eaten or burned. Gas is plants that sucked in C02 from millions of years ago and then we burn it releasing it back to teh atmosphere.
