i know that green leaves produce co2 after sunset but does a tree not NEED to release more co2 to survive....?

Question

do rain forests produce more co2 than they use?

Answer 1

Carbon dioxide is a waste product of cellular respiration. That is any cell that is releasing energy from food will give it off. Plant cells respire 24/7 just like animal cells. The main difference is that plants can use some of that carbon dioxide to trap energy in the form of sugar. We call this process photosynthesis. Plants use more carbon dioxide than they use. If they did not we would be in a heap of trouble. By the way the oxygen does not come from the carbon dioxide but the water the plant needs to carry on photosynthesis.

Answer 2

no, right the contrary - normally in the long term photosynthesis prevails over respiration and the plant grows (produces more mass that it uses - and FEEDS THE WHOLE ECOSYSTEM WITH THis MASS - bacause the other parts of cecosystem cant photosynthesize and are dependent on plants).

if respiration prevailed over photosynthesis in the long term (not only during night and winter), the plant will simply spend more mass than it produces - it wastes away - it can happen in unfavourable conditions. so a healthy rainforest produces more 02 than C02 in the long term and biomass (living and dead) accumulates in the long term.

-------------
in land ecosystems, the dead biomass should slowly accumulate over time (again photosynthesis prevails over the respiration - aerobic decomposition is the same process as respiration, chemically) or be in perfect balance - the amount of what grows on is eaten or decomposed - this balance that should be on Earth is lost because we burn oil and coal faster than ever.

also the compost - the organic fraction in soil - undergoes invisible decomposition due to poor management of agricultural land of due to forest felling - you know in forest the soil is moist and rich, in the field it is dead dirt because the compost turned into CO2 as the soil was exposed bare.! so if you fell a forest, not only the trees are lost and turned into C2, but also the CO2 starts escaping from soil rapidly.

Answer 3

green leaves needs CO2 for assimilation processes releasing O2 as a byproduct which mankind need for respiration. Hence, plants and humans go hand in hand by the assimilation and resperation processes.

Answer 4

very sturdy question. The solutions aspect out complexity to this short question. including to the previous solutions: partly it relies upon how warm the hearth is which varies because the hearth burns textile and decreases its gas provide. very warm fires actually transmit countless warmth with suggestions from radiation and may propagate the hearth to different timber without direct contact with them. Low temperature fires probable produce, somewhat, better Carbon Monoxide that may kill hearth warring parties rapidly, demanding to carry close if and at the same time as it occurs. yet, the radiation warmth is a higher threat, it really is why the take care of blanket is roofed with suggestions from a reflecting floor. intense temperature fires ought to burn lots of the roots and the carbon sequestered (buried) with suggestions from the tree and convey significantly better CO2 than burning an remoted tree of an identical length. yet, the warm temperature radiation also delivers the appropriate skill to discover wooded area fires shortly once they commence. Passive Infra-pink sensors were used in Vietnam to discover human beings boiling a pot of water from airplanes. we are now making use of this, for the first time, in California.

Answer 5

Tree use CO2 as we use O2....they convert CO2 into engery releasing 02....hence they do not produce more CO2 than they use!

Answer 6

Trees need light and co2 to photosynthesise, the by-product of this is oxygen, without light they cannot photosynthesise and therefore won't absorb co2.
