Oxegyn Cycle
Describe the Earth's oxegyn cycle
The oxygen cycle begins with the process of photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere, which humans and animals breathe in oxygen and breathe out carbon dioxide, and again linking back to the plants.
Describe Eaths nitrgeon cycle.
Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere.
Describe Earth's carbon cycle, including how energy from the sun drives Earth's carbon cycle
Plants constantly exchange carbon with the atmosphere. Plants absorb carbon dioxide during photosynthesis and much of this carbon dioxide is then stored in roots, permafrost, grasslands, and forests. Plants and the soil then release carbon dioxide when they decay.
What happens if CO2 is too low in the atmosphere?
Without carbon dioxide, Earth's natural greenhouse effect would be too weak to keep the average global surface temperature above freezing. By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperature to rise.
Why is nitrogen important?
Nitrogen is an essential nutrient for the production of amino acids, proteins, nucleic acids, etc., and stone fruit trees require an adequate annual supply for proper growth and productivity. Nitrogen is primarily absorbed through fine roots as either ammonium or nitrate.

What would happen if all carbon disappeared?
So even if carbon emissions stopped completely right now, as the oceans catch up with the atmosphere, the Earth's temperature would rise about another 1.1F (0.6C). Scientists refer to this as committed warming. Ice, also responding to increasing heat in the ocean, will continue to melt.
Is carbon more important than oxygen?
Carbon is in our current understanding of life, at least here on planet Earth, ALL life-forms are carbon based. However, not all need oxygen to survive or even oxygen to exist.
Explain the significance of the oxygen cycle in supporting life on earth.
The Oxygen Cycle is an essential biogeochemical Cycle to maintain the concentration and level of Oxygen in the atmosphere. The Oxygen Cycle is one of the main reasons for the existence of life on earth. Without Oxygen, the biosphere could not exist. However, Anaerobes can live without the presence of Oxygen.
Explain the role of microorganisms in Earth's nitrogen cycle.
Bacteria play a central role: Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates. Bacteria of decay, which convert decaying nitrogen waste to ammonia. Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
Describe the different forms taken by carbon and the reservoirs where they are found.
Most of Earth's carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles. Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
Can we live without CO2?
Carbon dioxide is a gas that is essential for life on Earth. Humans need carbon dioxide to regulate respiration and control blood pH. Plants use carbon dioxide to create oxygen through photosynthesis.
What is carbon and nitrogen together called?
Carbon nitrides are organic compounds consisting only of carbon and nitrogen atoms
What keeps the oxygen cycle going?
During photosynthesis, plants use sunlight, water, carbon dioxide to create energy and oxygen gas is liberated as a by-product of this process. Sunlight: Sunlight also produces oxygen. Some oxygen gas is produced when the sunlight reacts with water vapour in the atmosphere.
Explain the significance of the nitrogen cycle to life on Earth.
The nitrogen cycle matters because nitrogen is an essential nutrient for sustaining life on Earth. Nitrogen is a core component of amino acids, which are the building blocks of proteins, and of nucleic acids, which are the building blocks of genetic material (RNA and DNA).
Give examples of carbon forms found on Earth.
Carbon is found on Earth in the form of three different allotropes including amorphous, graphite, and diamond. Allotropes are materials made from the same element, but their atoms fit together differently.
How does global warming affect the carbon cycle?
For example, warming reduces the amount of CO2 absorbed by surface ocean waters and the amount of carbon sequestered in soils. It can also accelerate tree death and the risk of wildfires. Thawing permafrost may release additional carbon into the atmosphere.
Can we live without nitrogen?
It is nearly impossible to live without nitrogen.
What disrupts the oxygen cycle?
Human activities can have a negative impact on the oxygen cycle. For example, the burning of fossil fuels releases carbon dioxide into the atmosphere, which can lead to climate change. Climate change can disrupt the oxygen cycle by causing changes in temperature and precipitation patterns.
Explain how the Haber-Bosch process has affected the natural nitrogen cycle
The Haber–Bosch process is one of the largest contributors to a buildup of reactive nitrogen in the biosphere, causing an anthropogenic disruption to the nitrogen cycle. Since nitrogen use efficiency is typically less than 50%, farm runoff from heavy use of fixed industrial nitrogen disrupts biological habitats.
What is the biggest way humans mess up the carbon cycle?
Humans have a huge effect on the carbon cycle when we burn wood, fossil fuels (such as oil, coal, and natural gas), and other forms of carbon. This action releases the stored carbon into the atmosphere, where it becomes a greenhouse gas. Greenhouse gases are gases in the atmosphere that absorb and release heat.
Does carbon react with nitrogen?
Studies of the reaction of carbon with nitrogen from loo0 to 2200°C show that appreciable interaction takes place at temperatures as low as 1400°C. With one of the two types of graphite investigated, the rate of formation of cyanogen passes through a well-defined maximum at ca.
Can we live without oxygen?
No, after five to ten minutes of not breathing, you are likely to develop serious and possibly irreversible brain damage. The one exception is when a younger person stops breathing and also
