Up to a point, an increase of the reactant Carbon dioxide will increase the production of oxygen (increase the rate of photosynthesis). However, it will eventually change the ratio of CO2 and water as the CO2 increases, and the production of oxygen will decrease, (or in other words, the rate of photosynthesis decreases). This is one of the reasons why an increase of CO2 levels in the atmosphere is dangerous, as oxygen levels will decrease.

What environmental characteristics increase the rate of photosynthesis?
Factors affecting the rate of photosynthesis are 1) Light intensity: - the brightness which increases the rate of photosynthesis if increased 2) Light quality: - the color of the light (chlorophyll absorbs red and blue and reflects green, orange, and yellow so red and blue are preferable) 3) CO2 concentration: - the more CO2 the more photosynthesis will occur. 4) chlorophyll availability: - the more chlorophyll the more photosynthesis will occur. 5) water: - INDIRECTLY as if there is little water the plant will stop transpiration by closing the stomata keeping the water inside, but not allowing gaseous diffusion.
What factors increase or decrease the rate of photosynthesis?
carbondioxide: increase cO2- photosynthesis
Why is it important that you keep two variables constant such as light level and color while you're testing and how does a third variable CO2 level affect photosynthesis?
The first bit, "why is it important to keep to variables constant" is so you can be sure that the thing your measuring is what is affecting the change. So if your measuring the affect of CO2 levels on the rate of photosynthesis, you need to keep light level and any other variable constant through out the whole experiment so you know that it isn't a change in the amount of light that makes the rate of photosynthesis change but the change in CO2 level. I think that makes sense! Also, CO2 increases photosynthesis until a certain point at which photosynthesis can't happen any quicker because all the chlorophyll is 'taken up' using the CO2 for photosynthesis and so the only way to increase photosynthesis rate would technically be to add more chlorophyll. This means that CO2 becomes whats called a 'limiting factor'. I think that makes less sense!
Does the reduction of CO2 occur in respiration or photosynthesis?
photosynthesis respiration produces co2, uses o2 photosynthesis opposite
Products and byproducts of photosynthesis do not include o2c6h12o6 co2 h20?
CO2 is not a byproduct of photosynthesis.

Is photosynthesis responsible for atmospheric CO2?
Photosynthesis is responsible for lowering the levels of atmospheric CO2 since it is a requirement to make glucose. Cellular respiration produces CO2 as a by-product, so it is responsible for some atmospheric CO2.
When blood CO2 levels increase does the pH increase or decrease?
It decreases.
What do you think can affect the rate of photosynthesis?
The rate of photosynthesis will almost always decrease by whichever of several factors is lowest. Some of these include: 1)Sunlight - its Intensity & wavelength. 2)Temperature 3)CO2 and O2 - availability Sunlight Generally the more light there is the more photosynthesis occurs. This is true up to a point where the plant has reached maximum photosynthesis levels, so any increase in light intensity will not affect the plant further. Temperature Generally a higher temperature is better than cold temperatures for photosynthesis. However if it is humid and the air is saturated with water vapor, photosynthesis is limited. This is because the water vapor being expelled cannot leave and go into the air, as there isn't a concentration difference for it to diffuse across. So the water vapor sits in the leaf, stopping photosynthesis. CO2 Basically the more CO2 in the air, the better the rate of photosynthesis. Of course CO2 is taken in during the daytime, and if its content was less that normal, photosynthesis couldn't happen normally. Fertilizers increase the number of soil fungi and bacteria, thus increasing the levels of CO2 from their respiration and decomposition processes. Water and CO2 Plants need water for photosynthesis. If they lack it, they wilt. When they have a deficiency of water, their stoma close, so CO2 cannot diffuse into the leaves. So CO2 is also the limiting factor, although it is as a result of lack of water.
What happens to the rate of photosynthesis when the CO2 levels exceed 3 percent?
Photosynthetic rates could increase if a commensurate increase in photons per lea f area also increases, or is a a high enough level.
How will chlorophyll affect photosynthesis?
It does not affect. It is carrying out the process, water+light+CO2 --->glucose+O2.
Does carbon dioxide affect photosynthesis?
Photosynthesis is a processes plants use to harness the energy of light to convert carbon dioxide (CO2) & water into the simple sugar glucose. The larger the amount of co2, the more oxygen will be produced.

Why is the increase of co2 making sea levels rise?
The increase in carbon dioxide (CO2) is warming the planet. The oceans are expanding and the ice caps are melting causing sea levels to rise.
What effect is the destruction of forests likely to have atmospheric CO2 concentrations?
the increased CO2 levels since the destruction of forests will be fixed by photosynthesis
How does the pH in the blood change with an increase in the level of CO2?
An increase in blood CO2 levels will result in an increase in carbonic acid formation, and therefore lower the pH.
