Prediction-I think that as the light intensity increases, the rate of photosynthesis will as well.
what are the final products of photosynthesis
The next level of awareness might be the most common among people progressing beyond denial of FE’s possibility or existence. They and that there is no point in even trying. They are often those building bunkers to survive the coming collapse of global civilization. I have respect for that position, but it certainly will not help solve humanity’s problems or help the manifest. Nobody that I respected in the FE field ever felt hopeless. We all began our journeys naïvely, but never conceded defeat. When the , the miracle happened, so admitting defeat before even beginning does not seem productive or even realistic, and can lead to dysfunctional coping behaviors and even suicidal tendencies.
But in medieval Europe, the , beginning with Germanic lords as Rome was falling. Not only did the watermill spread throughout Europe, but new mills such as the and appeared. Today’s France is where most medieval mill innovations appeared, but watermills became universal on the streams and rivers of Europe. In 800, only a few watermills existed in Western Europe, but by 1000 there were hundreds. The of 1086 recorded nearly six thousand watermills in England alone, and the true number was some thousands more. The had 10 thousand watermills at that time, and their number doubled in the next two centuries, as did England’s. Each mill produced at least two-to-three horsepower, which was the equivalent labor of about 50 men. In 11th-century France, its mills produced the labor of a quarter of its population. Medieval European watermills produced the work of millions of people and reduced the need for slaves. It was a prelude to the Industrial Revolution. When Columbus sailed in 1492, watermills performed the work of at least 10 million people in Europe, which had a population of about 75 million. When watermill sites became filled, Europeans began using windmills, which first appeared in France in 1080, although the first . The social organization of medieval Europe was ; peasants labored for landowners in return for a portion of the harvest. The watermill became the center of a struggle between feudal and Church authorities and the peasantry; the windmill was established partly to circumvent lordly claims on waters that passed over their lands, as nobody yet owned the air.
What are the end products of Photosynthesis? | Yahoo …
In the photosynthesis takes place in a chloroplast of a thin-walled mesophyll cell and a 4-carbon acid is handed off to a thick-walled bundle sheath cell where the Calvin cycle occurs in a chloroplast of that second cell. This protects the Calvin cycle from the effects of .
Oxygen (Respiration), Food (Digestion)
In the process of photosynthesis, plants convert light (solar energy) into carbohydrates.
the end products of photosynthesis are glucose and oxygen Edit
The carbohydrates produced by photosynthesis form the foundation of nature's food chain; without them complex life forms, like man, would be incapable of surviving.
People are usually surprised to hear that grass is a relatively recent plant innovation. and only became common in the late Cretaceous, along with flowering plants. With grass, some , and grazers have been plentiful Cenozoic herbivores. According to , carbon dioxide levels have been falling nearly continuously for the past 150-100 million years. Not only has that decline progressively cooled Earth to the point where we live in an ice age today, but is currently considered the key reason why complex life may become extinct on Earth in several hundred million years. In the Oligocene, between 32 mya and 25 mya some plants developed a during photosynthesis known as . It allowed plants to adapt to reduced atmospheric carbon dioxide levels. C4 plants became in the Miocene, and grasses are today’s most common C4 plants and . The rest of Earth’s photosynthesizers use or , which is a water-conserving process used in arid biomes.

When sea levels rise as dramatically as they did in the Cretaceous, coral reefs will be buried under rising waters and the ideal position, for both photosynthesis and oxygenation, is lost, and reefs can die, like burying a tree’s roots. About 125 mya, reefs made by , which thrived on , began to displace reefs made by stony corals. They may have prevailed because they could tolerate hot and saline waters better than stony corals could. About 116 mya, an , probably caused by volcanism, which temporarily halted rudist domination. But rudists flourished until the late Cretaceous, when they went extinct, perhaps due to changing climate, although there is also evidence that the rudists . Carbon dioxide levels steadily fell from the early Cretaceous until today, temperatures fell during the Cretaceous, and hot-climate organisms gradually became extinct during the Cretaceous. Around 93 mya, , perhaps caused by underwater volcanism, which again seems to have largely been confined to marine biomes. It was much more devastating than the previous one, and rudists were hit hard, although it was a more regional event. That event seems to have , and a family of . On land, , some of which seem to have , also went extinct. There had been a decline in sauropod and ornithischian diversity before that 93 mya extinction, but it subsequently rebounded. In the oceans, biomes beyond 60 degrees latitude were barely impacted, while those closer to the equator were devastated, which suggests that oceanic cooling was related. shows rising oxygen and declining carbon dioxide in the late Cretaceous, which reflected a general cooling trend that began in the mid-Cretaceous. Among the numerous hypotheses posited, late Cretaceous climate changes have been invoked for slowly driving dinosaurs to extinction, in the “they went out with a whimper, not a bang” scenario. However, it seems that dinosaurs did go out with a bang. A big one. Ammonoids seem to have been brought to the brink with nearly marine mass extinctions during their tenure on Earth, and it was no different with that late-Cretaceous extinction. Ammonoids recovered once again, and their lived in the late Cretaceous, but the end-Cretaceous extinction marked their final appearance as they went the way of and other iconic animals.

Most plants produce seeds, which would have largely survived the catastrophe and began growing when conditions improved. Ferns came back first, in what is called a , as ferns are a . Crocodiles, modern birds (which included ), mammals, and amphibians also survived, and all could have found refuge in burrows, swamps, and shoreline havens, lived in tree holes and other crevices that they were small enough to hide in, and all could have eaten the catastrophe’s detritus. In general, freshwater species fared fairly well, especially those that could eat detritus. Also, the low-energy requirements of ectothermic crocodiles would have seen them survive when the mesothermic/ dinosaurs starved. The primary determinants seem to have been what could survive on detritus or energy reserves and what could not, and what could find refuge from the initial conflagration. While there may have been some evidence of dinosaur decline before the end-Cretaceous extinction (it was gradually growing colder), and the may have caused at least some local devastation, the complete extinction of non-avian dinosaurs, ammonites, marine reptiles, and others that would have been particularly vulnerable to the bolide event’s aftermath has convinced most dinosaur specialists that the bolide impact alone was sufficient to explain the extinction and no other hypothesis explains the pattern of extinction and survival that the bolide hypothesis does. In general, the key to surviving the end-Cretaceous extinction was being a marginal species, and all of those on center-stage paid the ultimate price. The end-Cretaceous extinction's toll was nearly 20% of all families, half of all genera, and about 75% of all species, and marked the end of an era; the Mesozoic ended and made way for the Age of Mammals, also called the , which used to have the .

appeared in the Mesozoic and required oxygen to form calcium carbonate. They became so abundant in the high oxygen of the late Cretaceous that the rain of their bodies on ocean floors gave the its name: chalk (the Latin name). Calcium carbonate, the primary constituent of limestone, comes in two forms: and . The magnesium content in the oceans, as well as the ocean temperature, determines which form of calcium carbonate will dominate. The also marked the end of a 100-million-year ice age and gave way to about 200 million years of hot times. During , Earth has . That pattern also seems . Hot seas are generally and cold seas are usually . Calcite seas create , which influence the biome that forms. The and periods had vast carbonate hardgrounds, which disappeared during the and returned in the Greenhouse Earth age of dinosaurs, becoming common in the Jurassic. Today’s Icehouse Earth has aragonite seas, so organisms that form calcium carbonate shells use aragonite, which is less stable than calcite and its formation is sensitive to temperature and acidity. Coral reefs, key phytoplankton (which help produce Earth’s oxygen), and shellfish use aragonite today to form their shells. There is already that acidification of the oceans due to humanity’s burning of fossil hydrocarbon deposits to power the industrial age is interfering with the ability of coral, carbonate-forming phytoplankton, and shellfish to form their shells. That is only one of the industrial age’s many deleterious ecosystem impacts. The current aragonite-formation situation is not a theoretical construct of fearful environmentalists, but is a .
