What nonmetals in the atmosphere and their combinations are essential to life on earth?
Oxygen, nitrogen, and yes, even carbon dioxide are essential to life on Earth (plants require carbon dioxide, in order to perform photosynthesis).
Carbon dioxide from the air is used to make sugars during what?
Carbon dioxide from the air is used to make sugars during the process of photosynthesis in plants. This process involves the utilization of sunlight, water, and chlorophyll to convert carbon dioxide into glucose, which is a form of sugar used for energy storage.
What Producers like this plant take in oxygen and release carbon dioxide during what?
Producers like plants take in oxygen and release carbon dioxide during the process of cellular respiration. While they primarily use photosynthesis to convert carbon dioxide and sunlight into oxygen and glucose, cellular respiration occurs in their cells to break down glucose for energy, resulting in the release of carbon dioxide as a byproduct. This process happens continuously, even at night when photosynthesis ceases.
Explain why at certain times of a day there is no movement of oxygen or carbon dioxide through stomata even though they are open.?
It might be that at certain times there is a balance between the amount of photosynthesis and the amount of cellular respiration going on. Photosynthesis produces the oxygen that respiration needs. Respiration produces the carbon dioxide that photosynthesis needs.
What is the role of living organisms in the carbon cycle?
Animal's role in the carbon cycle is the exchange of carbon dioxide and oxygen between plants. Plants need carbon dioxide for photosynthesis, and the byproduct is oxygen that all living things need to live. Then animals breath out carbon dioxide to be in taken by plants.
What happens if plants get too much carbon dioxide?
The plants would have a harder time growing. Carbon Dioxide is similar for plants as Oxygen is for people. However, plants can often adapt to changes in "air quality" much better then people can.
How does photosynthesis help combat global warming?
during photosynthesis, plants use co2 as one of their reactant and produce oxygen. with less plants/trees, more co2 are being trapped within the atmosphere which makes global warming and influences the climate.
Is carbon dioxide a chemical property?
No, carbon dioxide is not a chemical property. In fact, it isn't even a property. It is a molecule.
What is the relationship between light intensity and carbon dioxide concentration?
The relationship between light intensity and carbon dioxide concentration is critical in photosynthesis. Higher light intensity typically increases the rate of photosynthesis, as it provides more energy for the process. However, this effect is often dependent on the availability of carbon dioxide; if CO2 concentration is low, the photosynthetic rate may not increase significantly even with high light levels. Thus, both factors work together to influence plant growth and productivity.
What decreases the amount of carbon dioxide in the atmosphere?
The planet has a number of huge carbon sinks, removing CO2 from the atmosphere. The largest is the ocean, as CO2 dissolves. This absorbs roughly 80% of all carbon dioxide. Other sinks are photosynthesis by vegetation and phytoplankton, and the weathering of silicate rock. For more details, read about the carbon cycle. Currently, sources of carbon must outweigh the sinks because atmospheric CO2 is increasing globally by roughly 2 parts per million by volume per year, as can be seen in the NOAA measurements of atmospheric CO2. CO2 is even higher in cities and industrial areas, in places where fossil fuels are being burnt in quantity. The easiest way for us to reduce the carbon dioxide levels is to reduce carbon dioxide emissions. This is the scientific consensus view, and is the view held by the IPCC, all major scientific bodies and national academies of science around the world.
Why is there less carbon dioxide in the atmosphere in summer and spring?
During spring and summer more plants photosynthesize, removing carbon dioxide from the atmosphere. In fall and winter fewer plants are active, and some even die and decay, which releases carbon dioxide. This is more pronounced in the northern hemisphere which contains the most land mass and therefore the most plant life.
How are trees important to Earth?
Trees help to keep us breathing they give us fresh air to breathe. They also take carbon dioxide out of the air through photosynthesis. They release the oxygen and store the carbon. About half the weight of a tree is carbon. This is important because carbon dioxide is a greenhouse gas that we are adding to the atmosphere every time we drive a car or even use electricity.
