What are the similarities and differences between the carbon cycle and nitrogen cycle? | Socratic
Hydrologic Cycle (Water Cycle); Carbon Cycle; Carbon Cycling Nitrogen is only fixed by bacteria and archea, and they fix 85% of the 15 giga tons of . (or from biocarbonates dissolved in water) by plants, photosynthetic bacteria, and For the biological links, the carbon cycle comes full cycle when carbon is. Describe how human actions interfere with the natural carbon cycle. Through photosynthesis, the inorganic carbon in carbon dioxide plus water and energy from . Nitrogen fixing bacteria either live free or in a symbiotic relationship with. Carbon Cycle: There are many important processes in the carbon cycle that primarily relate to photosynthesis, decomposition, and deposition.
In the respiration cycle, fauna, or animal life inhabiting the biosphere, consume carbohydrates in the form of plant life and oxygen and output carbon dioxide, water and energy.
The animals use the energy produced to power their biology. Sciencing Video Vault Carbon Cycle: Photosynthesis Flora, the ecosystem's plant life, perform photosynthesis.
Plants take in energy from the sun, carbon dioxide and water and produce carbohydrates and oxygen. These carbohydrates and oxygen are readily used by the fauna present in the ecosystem. In addition to being consumed by animal life, some of these carbohydrates return to the earth when the flora die. There, they break down and the carbon returns to the ecosystem in the form of carbon dioxide. If not consumed by animals, carbon from decaying plants will eventually convert into fossil fuels.
Nitrogen Cycle Most of the nitrogen found in ecosystems exists as nitrogen gas.
The nitrogen in the atmosphere is very stable and does not combine easily with other elements. Lightning has sufficient energy to convert nitrogen into nitrates, a form of nitrogen usable by plant life.
What are the similarities and differences between the carbon cycle and nitrogen cycle?
The second way nitrogen is converted to nitrates is by nitrogen fixing bacteria. These bacteria use special enzymes to convert nitrogen to nitrates.
Plants use these nitrates to form amino acids. They are the water, carbon and nitrogen cycles. We will go into depth with each cycle. Water Cycle Within the water cycle, energy is supplied by the sun, which drives evaporation whether it is from the ocean surfaces or from treetops and leaves.
The sun, with the help of wind, also supplies the energy, which drives the weather systems, which moves the water vapors, in the form of clouds, from one place to another, or else it would only rain over oceans.
Precipitation occurs when water condenses from a gaseous state in the atmosphere and then falls to earth. Evaporation is the reverse process where liquid water becomes gaseous.Cycles. Water, Carbon, Nitrogen, Oxygen and Phosphorus
Once water condenses, gravity takes over and the water is pulled to the ground. Gravity continues to operate, either pulling the water underground or groundwater across the surface also called runoffeither way gravity goes on to pull water lower and lower until it reaches the oceans.
Frozen water ice may be trapped at the cooler regions of the Earth such as the poles, glaciers and on mountain as snow or ice, and may remain as such for very long periods. Lakes, ponds, and wetlands form where water is temporarily trapped and stored.
The oceans are salty because any erosion of minerals that occurs as the water runs to the ocean will add to the mineral content of the ocean water. Water cannot leave the oceans except by evaporation, and evaporation leaves the minerals behind.
Thus, rainfall and snowfall are comprised of relatively clean water, with the exception of pollutants that are picked up, as the waste falls through the atmosphere, an example of this would be acid rain. Organisms play an important role in the water cycle.
The water is not contained for a long time and moves out of the organism quickly in most cases.
In plants, water is drawn in at the roots and moves to the gas exchange organs, the leaves, where it evaporates quickly. This special case is called transpiration because it is responsible for so much of the water that enters the atmosphere. In both plants and animals, the breakdown of carbohydrates sugars to produce energy respiration produces both carbon dioxide and water as waste products.
Photosynthesis reverses this reaction, and water and carbon dioxide are combined to form carbohydrates. Now you understand the relevance of the term carbohydrate; it refers to the combination of carbon and water in the sugars we call carbohydrates. From a biological perspective, the key events here are the complementary reactions of respiration and photosynthesis.
How does the carbon cycle relate to photosynthesis and respiration? | Socratic
Respiration takes carbohydrates and oxygen and combines them to produce carbon dioxide, water, and energy. Photosynthesis takes carbon dioxide and water and produces carbohydrates and oxygen. This might sound a little confusing but, the outputs of respiration are the inputs of photosynthesis, and the outputs of photosynthesis are the inputs of respiration.
The reactions are also complementary in the way they deal with energy. Photosynthesis takes energy from the sun and stores it in the carbon-carbon bonds of carbohydrates; respiration releases that energy.
