Are plants / trees net producers OR consumers of carbon-di-oxide ?

Question

what are the results of controlled studies ?

Answer 1

they consume CO2 to photosynthesize

Answer 2

Trees are net consumers of CO2 for as long as they are living and growing. If they are cut down and burnt, the burning releases CO2 back into the atmosphere. If they die naturally and rot, the organisms feeding upon the tree release a mix of methane and CO2, again back into the atmosphere, though not perfectly. Some carbon will remain on the ground and eventually get buried.

The only way to remove a mass of carbon out of the atmosphere, is to put it somewhere else -- either dissolve it into the sea or put it into back into the ground.

Answer 3

Net consumers of CO2 with a waste product of Oxygen. The oxygen used by the same plant is less than the oxygen produced. Otherwise, we would all be in sorry shape..actually, we wouldn't be in any shape at all...we would have long ago been extinct.

Answer 4

Temperate forests are largely carbon neutral. They release as much carbon seasonally as they absorb, maybe a slight amount net oxygen. Temperate forests have dark leaves that may absorb as much infrared which negates the warming the absorbed carbon would have. Unless the tree's have long lifespans (Redwood, Eucalypts, Cedar) or if the tree's are geologically isolated (buried) Tropical reforestation is the real means of dealing with carbon dioxide. Tropical deforestation accounts for a quarter of all greenhouse gas emissions.

Answer 5

Plants or tree or flora... they give out oxygen and consume carbondioxide at the day light.

While at night they consume Oxygen juz like normal human being and give out carbondioxide.

Thus, it is not very advisable for us to sit under the tree at night due to this fact.

Answer 6

they are net consumers of carbon dioxide which they utilize during producing glucose in photosynthesis and if it wasnt so all organisms living on this earth would have suffocated and eliminated by now

Answer 7

consumers, the C from the co2 they consume goes into the sugar they make to build themselves with. The O goes into the atmosphere. Some also goes into the sugars they make.

Answer 8

Photosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend.

Green Plants and Photosynthesis






Green Plants and Photosynthesis
All of our food ultimately results from the process of photosynthesis in green plants and algae. The pigment chlorophyll is responsible for the green color of plants as well as their ability to photosynthesize. In common terrestrial plants photosynthesis is usually carried out in the leaves, although it can also occur in the stem or other parts of the plant.

Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. These organisms are veritable sugar factories, producing millions of new glucose molecules per second. Plants use much of this glucose, a carbohydrate, as an energy source to build leaves, flowers, fruits, and seeds. They also convert glucose to cellulose, the structural material used in their cell walls. Most plants produce more glucose than they use, however, and they store it in the form of starch and other carbohydrates in roots, stems, and leaves. The plants can then draw on these reserves for extra energy or building materials. Each year, photosynthesizing organisms produce about 170 billion metric tons of extra carbohydrates, about 30 metric tons for every person on earth.

Photosynthesis has far-reaching implications. Like plants, humans and other animals depend on glucose as an energy source, but they are unable to produce it on their own and must rely ultimately on the glucose produced by plants. Moreover, the oxygen humans and other animals breathe is the oxygen released during photosynthesis. Humans are also dependent on ancient products of photosynthesis, known as fossil fuels, for supplying most of our modern industrial energy. These fossil fuels, including natural gas, coal, and petroleum, are composed of a complex mix of hydrocarbons, the remains of organisms that relied on photosynthesis millions of years ago. Thus, virtually all life on earth, directly or indirectly, depends on photosynthesis as a source of food, energy, and oxygen, making it one of the most important biochemical processes known.

Answer 9

they are net consumers and in turn produce oxygen without which no animal could survive on this planet.

Answer 10

net consumers. They are good for absorbing pollutants, like CO2, and CO!
