What do plants do with CO2 present in the atmosphere?

Answer 1

It is used in the light independent reaction of photosynthesis where it is combined with a 5-carbon molecule called ribulose bisphosphate using an enzyme to form two molecules of the 3-carbon molecule called glycerate-3-phosphate. This is then reduced by ATP and reduced NAD from the light dependent reaction into two molecule of triose phosphate, some of which is then converted to organic substances such as glucose. This is how energy enters an ecosystem and then consumers and herbivores take up this energy by eating the plant or another animal who has eaten the plant and thereby obtaining the glucose.

they use it for energy in photosynthesis and it is converted into carbohydrates- or sugars- because they, unlike us can create their own energy, we just use it

Answer 2

Plants do not change the Earth's atmosphere. Plants maintain the stable amount of oxygen and carbon dioxide in the atmosphere.

Since humans breathe in oxygen and give out carbon dioxide, plants do the opposite during photosynthesis in the day, so as to reduce carbon dioxide in the environment. This is part of the natural carbon cycle. However, other industrial activities have been burning fossil fuels, giving out way too much carbon dioxide, and together with the clearing of forests, this has led to a significant increase in the amount of carbon dioxide in the air.

Answer 3

Fixes it into intermediate molecules that become glyceraldehyde-3-phosphate in the Calvin cycle which the plant can use to make a variety of sugars with; both for energy and building materials.

Answer 4

Through photosynthesis, by binding it to carbon based compounds like sugars with the use of lots and lots of energy

Answer 5

It takes the carbondioxide and produces food by the process of photosynthesis.

co2 + chlorophyll + water + sunlight = carbohydrate + energy
