Why do atmospheric carbon dioxide concentrations fluctuate seasonally?
Atmospheric carbon dioxide concentrations fluctuate seasonally due to the natural processes of photosynthesis and respiration in plants. During the growing season, plants take in carbon dioxide for photosynthesis, which reduces the amount of CO2 in the atmosphere. In the winter, when plants are dormant, there is less photosynthesis and more respiration, leading to an increase in atmospheric CO2 levels.
Why is the amount of carbon dioxide highest during midnight and lowest at 12 noon?
Actually carbon dioxide concentration increases at midnight and decreases at dawn At night the concentration is higher because plants take in oxygen and breathe out carbon dioxide at night so the concentration is higher. At dawn the concentration is lower because, plants breathe in oxygen at daytime and breathe out CO2 so the concentration is lower.
Why do carbon dioxide levels change seasonally?
Carbon dioxide levels change seasonally due to the natural processes of photosynthesis and respiration in plants. During the spring and summer months, plants take in carbon dioxide for photosynthesis, which reduces the levels in the atmosphere. In the fall and winter, when plants go dormant or lose their leaves, respiration releases carbon dioxide back into the atmosphere, causing an increase in levels.
What greenhouse gas is harmful when its concentration increases in the atmosphere?
Carbon dioxide (CO2) is a harmful greenhouse gas when its concentration increases in the atmosphere. This increase is primarily due to human activities such as burning fossil fuels and deforestation, leading to global warming and climate change.
Which process does not release carbon dioxide to the atmosphere?
Photosynthesis is a process that does not release carbon dioxide to the atmosphere. Instead, during photosynthesis, plants absorb carbon dioxide from the environment and convert it into oxygen through a series of chemical reactions.
What happens when you increase the amount of co2 given to plants?
The rate of photosynthesis increases. Carbon dioxide is a reactant in photosynthesis; if the reactants are increased, the reaction goes faster.
What would happen if carbon dioxide in the air increases around a plant?
The rate of photosynthesis will increase, if light is not a limiting factor
How does changing the light intensity effect photosynthesis and why?
By changing the light intensity the rate of photosynthesis will either increase or decrease because it is one of the factors that affects photosynthesis. If you increase the light intensity the rate increases but if you decrease the light intensity the rate decreases.
What processes increase carbon dioxide and oxygen in the atmosphere?
Processes that increase carbon dioxide in the atmosphere include burning fossil fuels, deforestation, and industrial activities. Photosynthesis by plants and algae is a key process that increases oxygen in the atmosphere.
WHY DOES THE CONCENTRAtion of oxygen increase as the light intensity increases?
As light intensity increases, the rate of photosynthesis in plants also increases. This results in the plant consuming more carbon dioxide and producing more oxygen as a byproduct. Therefore, the concentration of oxygen increases as the light intensity increases.
Does the amount of light affect the rate of photosynthesis?
As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. As the rate increases, eventually another factor will come into short supply. The graph below shows the effect of low carbon dioxide concentration.
Which process increases the amount of oxygen and decreases the amount of carbon dioxide in the atmosphere?
Photosynthesis by green vegetation and forests.
Why would an increase in CO2 cause a plant to grow faster?
Plants grow better if the amount of carbon dioxide in the air increases because plants breathe in carbon dioxide in order to use it in their life process. Plants expel oxygen, and people expel carbon dioxide, plants and people are one of natures perfect symbiotic relationships.
Which factor would not increase the production of glucose by photosynthesis in plants?
excess carbon dioxide
Breathing rate is most likely to increase if the blood concentration?
If the blood concentration of carbon dioxide increases, the breathing rate is most likely to increase. This occurs as a response to remove excess carbon dioxide from the body and maintain a balance of oxygen and carbon dioxide levels in the blood.
What is the conclusion importance of photosynthesis in maintaining a balance ecosystem?
Photosynthesis is very important in maintaining a balance in the ecosystem. Carbon dioxide is used by the plants for photosynthesis and oxygen which is used by animals is the by product of photosynthesis.
What will be the effect of too much carbon dioxide in the atmosphere to photosynthesis?
Too much carbon dioxide in the atmosphere can initially increase rates of photosynthesis, as it is a key component for the process. However, excessive levels of carbon dioxide can eventually lead to decreased photosynthetic efficiency, disrupting plant growth and potentially impacting ecosystems.
