Explain why carbon dioxide concentration affects the productivity of plants?

Carbon dioxide is food for plants, more CO2, more assimilation.

Carbon dioxide, because that is the raw material required for photosynthesis

there are various factors which affects rate of reaction. like temperature,pressure and concentration of the reactants involved. and they all have different effects

Sunlight is necessary for plants to grow, and to provide energy to warm the earth's atmosphere. Light intensity controls plant growth. Light duration affects plant flowering and animal/insect habits.\n\nNow, during photosynthesis, sunlight energy is used to power chemical reactions that combine water with the air's carbon dioxide to form starchy carbohydrate. In other words, during photosynthesis, sunlight energy is stored in carbohydrate for later use. Here's the simplified chemical formula for photosynthesis:\n\n6CO2 + 12H2O + sunlight ---> 6O 2 + C6 H12O 6 + 6H2 O\nor...\ncarbon dioxide + water + sunlight ---> \noxygen + carbohydrate + water \n \n\nSome carbohydrate remains in the leaf but mostly it's transported elsewhere in the plant, perhaps into the stem, or maybe into special underground storage areas, such as the potato plant's potatoes.

Yes, they can. \nHumans produce carbon dioxide (CO2) through respiration: \nC6H12O6 + 6O2 --> 6CO2 + 6H20\nPlants then use the carbon dioxide in photosynthesis:\n6CO2 + 6H2O --> C6H12O6 + 6O2\n\nNote that C6H12O6 is glucose. \n\nHope that helps! =)

Plants need a number of things to grow. They need water from the soil, energy from the sun, carbon dioxide from the air and they need nutrients.  Very often one or more of these resources are limiting so that the plant can not grow as big as it would otherwise. Often the most limiting resources are water or nutrients. This can be helped by irrigation in the case of water or by fertilisers in cases were nutrients are deficit. Nutrients are building blocks in the plant. For example nitrogen, which is most abundant in the plant except for carbon, is an important element in \nproteins, as is sulphur. Magnesium is needed in the chlorophyll so that the plants can gain energy from sunlight. These elements can be given to the \nplants by fertilising the soil. Nitrogen, phosphorous and potassium are generally given in the largest amounts. Sulphur, magnesium, copper, zinc and so on are given much sparse and are called micronutrients. Carbon is \nnot a nutrient in the same way, as the roots do not take it up. It is assimilated in needed quantities from the air as carbon dioxide.

rice,wheat,potato,etc...r some of the C-3 plants.....when they r exposed to co2(14),they produce 3C compound called phosphoglyceric acid.....this occurs only in mesophyll cells at an optimum temp of 20-25 degree C. Here photorespiration rate is high & leads to loss of fixed CO2. It also decreases CO2 fixation rate....

2 stages of photosynthesis work together to produce\nglucose by..... first capturing the sun's energy then in the chloroplasts, water and carbon dioxide undergo chemical reactions which produce sugar including glucose..........

Climate is affected by a number of sources such as where your location is to the equator, the earths rotation, etc. Long term changes are taking place very slowly due to human activities (gases, deforestation, soil erosion etc) and need to be addressed on a global level to prevent further changes. Increased gases in the atmosphere cause heating...and deforestation and decrease of plant life means that many of the carbons are not being used - so they continue to increase in the atmosphere causing changes. \nThere is no way to "stop" it, just slow it by us being more energy efficient, stop creating so much pollution...\nYou can somewhat effect microclimates - a local area that is changed because of large cities, large mountains etc - but not really hard to do intentionally - it's done over time as something builds up and disturbs the existing temp.\n\nWhew...that was a long one.

Close because the plant takes in CO2 and so it will prevent any CO2 from leaving the cell because it need them to carry out photosynthesis. Once they have enough, the stomata are closed so that they don't escape.

The vibration is the ingredient that promotes an increase in the growth of the plant.  I believe more carbon dioxide would be supplied to the plant by the vibration and the growth would increase.

For photosynthesise CO2 and sunlight required.When we breath,we discharge CO2.This CO2 can help plants for photosynthesise.Any way we producing more than million times of CO2 what plants required other than our breathing.Plants tired of this process.If you want relay help plants,reduce wastage and pollution.

B.\n\nCellular respiration uses Oxygen and releases CO2, and at Nighttime, Photosynthesis cannot occur(since there is a lack of light) and therefore cannot convert CO2 to O2, hence lowering the concentration

Because there isn't a natural process kicking out more of them. Photosynthesis actually synthesizes more of the biotic elements in plants that we find useful.\n\nThe difference is, as your own question alludes to, the same as that between new manufacturing and recycling.

Yes,CO binds to mitochondrial cytochrome oxidase and impairs oxidative phosphorylation and causes cell damage.So CO adversely affect respiration in plants.Carbon monoxide increases the amount of other greenhouse gases (methane), and eventually oxidises into the greenhouse gas, carbon dioxide. Greenhouse gases are linked to global warming.
