Carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur are conserved and recycled in the atmosphere, on land, in water, or beneath the earth's surface.
Materials are recycled via erosion, weathering, water drainage, and the movement of tectonic plates
.
How are carbon and nitrogen cycled through an ecosystem?
Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere
. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants.
What are the 3 ways that carbon is cycled through an ecosystem?
- Carbon moves from the atmosphere to plants. …
- Carbon moves from plants to animals. …
- Carbon moves from plants and animals to soils. …
- Carbon moves from living things to the atmosphere. …
- Carbon moves from fossil fuels to the atmosphere when fuels are burned. …
- Carbon moves from the atmosphere to the oceans.
How is oxygen cycled in the ecosystem?
Plants and animals
use oxygen to respire and return it to the air and water as carbon dioxide
(CO
2
). … CO
2
is then taken up by algae and terrestrial green plants and converted into carbohydrates during the process of photosynthesis, oxygen being a by-product.
How does oxygen occur in nature explain oxygen cycle in nature?
Oxygen from the atmosphere is used up in three processes, namely combustion, respiration and in the formation of oxides of nitrogen
. Oxygen is returned to the atmosphere by the process called as photosynthesis. Was this answer helpful?
Which of the following processes produces oxygen in the oxygen cycle?
Plants – Plants create the majority of the oxygen we breathe through a process called
photosynthesis
. In this process plants use carbon dioxide, sunlight, and water to create energy. In the process they also create oxygen which they release into the air.
How does nitrogen cycle through the ecosystem?
Plants take up nitrogen compounds through their roots. Animals obtain these compounds when they eat the plants. When plants and animals die or when animals excrete wastes, the nitrogen compounds in the organic matter re-enter the soil where they are broken down by microorganisms, known as decomposers.
Why are carbon and nitrogen cycles important to ecosystems?
Their cycles
regulate how much water/nitrogen/carbon/oxygen there is in one ecosystem and how quickly they will be replenished over time
. So the cycles regulate both the species present in an ecosystem and in what quantities, as well as the changes through time of that ecosystem (seasonally, annually, etc).
How do plants and animals obtain carbon hydrogen nitrogen and oxygen?
Plants obtain carbon by taking in carbon dioxide in the leaves. They get hydrogen by photosynthesis. They get nitrogen by by photosynthesis. They get oxygen by photosynthesis.
What is the carbon oxygen cycle?
The Oxygen-Carbon Dioxide Cycle
During photosynthesis, plants give off oxygen as a waste product.
Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves. Oxygen moves out of the plant leaf through these same openings.
What are the various steps of nitrogen cycle?
- Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
- Nitrification (NH3 to NO3-)
- Assimilation (Incorporation of NH3 and NO3- into biological tissues)
- Ammonification (organic nitrogen compounds to NH3)
- Denitrification(NO3- to N2)
How do carbon and oxygen move through an ecosystem?
When they're exposed to light, green plants use carbon dioxide from the atmosphere to manufacture living matter and release oxygen into the air
. This process is called photosynthesis. Carbon dioxide is produced through the respiration of animals and plants, which consume oxygen and release carbon dioxide.
What processes are most directly involved in the cycling of carbon and oxygen between plants and animals in an ecosystem?
The chemical equation for
photosynthesis
is below: Plants and animals engage in the reverse of photosynthesis, which is respiration. In respiration, animals use oxygen to convert the organic carbon in sugar into food energy they can use. Plants also go through respiration and consume some of the sugars they produce.
Which two processes in the carbon cycle are also part of the oxygen cycle?
In the natural carbon cycle, there are two main processes which occur:
photosynthesis and metabolism
. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
Which of the following recycles substances such as water oxygen carbon and nitrogen in an ecosystem?
Decomposers
break apart complex organic materials into more elementary substances: water and carbon dioxide, plus simple compounds containing nitrogen, phosphorus, and calcium. All of these components are substances that plants need to grow.
How is oxygen formed in nature?
Oxygen is
generated during photosynthesis by plants and many types of microbes
. Plants both use oxygen (during respiration) and produce it (via photosynthesis). Oxygen can also form a molecule of three atoms, which is known as ozone (O
3
).
What process makes nitrogen available to plants and animals?
When nitrogen is absorbed by the soil, different bacteria help it to change states so it can be absorbed by plants. Animals then get their nitrogen from the plants.
Fixation – Fixation is the first step in the process of making nitrogen usable by plants.
How are the carbon oxygen and nitrogen cycles vital to sustaining life on earth quizlet?
How are the carbon, oxygen, and nitrogen cycles vital to sustaining life on Earth? Carbon, oxygen, and nitrogen are vital components of life on Earth. The carbon, oxygen, and nitrogen cycles
allow vital elements to return to usable form by organisms
.
How does the carbon cycle work?
The carbon cycle is nature's way of
reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again
. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
What three natural processes cause the cycling of oxygen and carbon dioxide?
Respiration, combustion and decomposition
are three other ways that CO
2
and/or oxygen is released back into the atmosphere. Another biogeochemical cycle, the hydrogen cycle, connects some of the pathways in nature that are involved in the carbon and oxygen cycles.
How is nitrogen cycled through biotic and abiotic components of an ecosystem?
The nitrogen cycle
moves nitrogen back and forth between the atmosphere and organisms
. Bacteria change nitrogen gas from the atmosphere to nitrogen compounds that plants can absorb. Other bacteria change nitrogen compounds back to nitrogen gas, which re-enters the atmosphere.
Which step in the carbon cycle involves the transformation of carbon dioxide into oxygen?
The process of oxygen generation is called
photosynthesis
. During photosynthesis, plants and other producers transfer carbon dioxide and water into complex carbohydrates, such as glucose, under the influence of sunlight.
What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles?
Much of the overlap between the carbon cycle and the nitrogen cycle
occurs in the soil, in processes conducted by soil microbes
. Microbes break down nutrients, build new compounds for their own growth, and eventually die.
