How do human beings contribute to the phosphorus and sulfur cycles?
Human beings contribute to the phosphorus cycle by extracting phosphorus from the earth for use in fertilizers and then releasing excess phosphorus into water bodies through agricultural runoff. In the sulfur cycle, human activities such as burning fossil fuels and mining operations release sulfur dioxide into the atmosphere, which can then contribute to acid rain and alter ecosystem dynamics.
What is oxygen-carbon dioxide cycles?
The oxygen-carbon dioxide cycle is the process by which carbon dioxide is converted into oxygen through photosynthesis by plants, and then oxygen is converted back into carbon dioxide through respiration by living organisms. This cycle is essential for maintaining the balance of oxygen and carbon dioxide in the atmosphere, which is crucial for sustaining life on Earth.
How can carbon be passed from plants and animals to human beings?
when plants and animals respire, carbon is returned to the air as carbon dioxide, and humans then beathe in the same carbon dioxide that was placed into the air by the decomposed plants and animals.
How does carbon dioxide affect carbon cycle?
It allows more water to evaporate in the atmosphere.
What prevents carbon dioxide a metabolic byproduct from lowering the pH of blood in human beings?
In human beings, carbon dioxide is converted to bicarbonate ions by an enzyme called carbonic anhydrase in the red blood cells. This bicarbonate helps maintain the pH balance in the blood by acting as a buffer, preventing excessive acidification. Additionally, the lungs regulate the levels of carbon dioxide by exhaling it, thus preventing a buildup that could lower blood pH.
What are 2 ways animals contribute to the carbon cycle?
Human beings contribute to the carbon cycle through the burning of biomass like coal and gasoline. They also contribute through deforestation which limits the earths ability to process the excess carbon.
How do human beings contribute to the phosphorus and sulfur cycles?
Human beings contribute to the phosphorus cycle by extracting phosphorus from the earth for use in fertilizers and then releasing excess phosphorus into water bodies through agricultural runoff. In the sulfur cycle, human activities such as burning fossil fuels and mining operations release sulfur dioxide into the atmosphere, which can then contribute to acid rain and alter ecosystem dynamics.
How does carbon enter the carbon cycle?
Carbon enters the carbon cycle through various processes such as photosynthesis by plants and algae, respiration by living organisms, volcanic eruptions releasing CO2, and the decay of organic matter by decomposers. Human activities such as burning fossil fuels and deforestation also contribute to the carbon cycle.
What is given off by human beings that is used by plants?
carbon dioxide
What is the role of carbon dioxide in the carbon dioxide diagram and how does it contribute to the overall understanding of the carbon cycle?
In the carbon cycle diagram, carbon dioxide plays a crucial role as a greenhouse gas that traps heat in the Earth's atmosphere. This contributes to global warming and climate change. Understanding the role of carbon dioxide in the carbon cycle helps us grasp how human activities, such as burning fossil fuels, impact the balance of carbon in the environment and the Earth's climate.
Why do we breathe out more carbon dioxide than you breathe in?
because we are human beings
What is carbon dioxide-oxygen cycle?
Oxygen-Carbon Dioxide Cycle- a continuous exchange of oxygen and carbon dioxide by plants and animals including human
What is oxygen carbon dioxide cycle?
Oxygen-Carbon Dioxide Cycle- a continuous exchange of oxygen and carbon dioxide by plants and animals including human
How is carbon exchanged between humans and plants?
carbon is released by the human which is enhaled by the human n there fore the cycle moves on
Which toxic gases in the environment lowers the resistance to pneumonia in human beings?
carbon dioxide
What human activities contribute to the increase of carbon dioxide in the atmosphere?
Human activities that contribute to the increase of carbon dioxide in the atmosphere include burning fossil fuels for energy, deforestation, and industrial processes.
At what point does human activity affect the natural cabon cycle?
Human activity affects the natural carbon cycle mainly through the burning of fossil fuels, deforestation, and land-use changes. These activities release excessive amounts of carbon dioxide into the atmosphere, leading to an imbalance in the carbon cycle and contributing to global warming.
