Carbon dioxide does not leave the atmosphere into space, but rather back to the earth and the oceans. Much of it is taken up by plants through photosynthesis, while much of the remainder is taken up by oceans. Oceans, however, also outgas a considerable amount, so it is not just a one-way transport.
What else can I help you with?
What enters and leaves atmosphere?
The atmosphere exchanges various gases and particles with the Earth's surface and space. Key components that enter the atmosphere include water vapor, carbon dioxide, and oxygen from biological processes like photosynthesis and respiration, as well as pollutants from human activities. Conversely, substances such as carbon dioxide and methane can leave the atmosphere through processes like absorption by oceans and vegetation. Additionally, particles from space, such as meteoroids, enter the atmosphere regularly, while gases can escape into space under certain conditions.
What do plants get from the atmosphere?
Plants primarily obtain carbon dioxide from the atmosphere, which they use in the process of photosynthesis to produce glucose and oxygen. They also absorb water vapor through their leaves, which plays a role in transpiration and nutrient transport. Additionally, plants can benefit from trace gases such as nitrogen, which can be utilized by certain species for growth and development.
How fast does a space shuttle need to be traveling when it leaves the earths atmosphere?
A space shuttle needs to reach a speed of approximately 17,500 miles per hour, known as orbital velocity, to successfully leave the Earth's atmosphere and enter space. This speed allows the shuttle to counteract the pull of Earth's gravity and achieve a stable orbit around the planet.
Can leaves make food at night?
No, leaves cannot make food at night because they require sunlight to carry out photosynthesis, the process by which they convert water and carbon dioxide into glucose and oxygen. Therefore, leaves cannot produce food in the absence of sunlight.
Why is there oxygen on the earth and not on the planets?
Originally the earth had only a small amount of oxygen and abundant carbon dioxide. Primordial green algae first evolved to take advantage of this carbon dioxide and produced the oxygen as a by product. Over billions and billions of years, and as additional plant species evolved, the atmosphere was transformed into the oxygen rich environment we have today.
Where does the leaf carbon dioxide?
From the atmosphere, of course. There is a small amount of carbon dioxide in the atmosphere and plants take in this gas through the stomata of their leaves and use it to construct sugars.
What is taken in from the atmosphere through leaves to make food for a plant?
Carbon dioxide is taken in from the atmosphere through the leaves during photosynthesis. This carbon dioxide is then used along with water and sunlight to produce glucose, which is the food that plants need to survive and grow.
Plants absorb the greenhouse gas carbon dioxide during the process of .?
All trees, leaves and growing vegetation absorb carbon dioxide from the atmosphere.
What Plants absorb the greenhouse gas carbon dioxide during the process of growing?
All trees, leaves and growing vegetation absorb carbon dioxide from the atmosphere.
Where do the carbon atoms come from to produce the certain sugar for photosynthesis?
The carbon atoms used to produce sugars during photosynthesis primarily come from carbon dioxide in the atmosphere. Plants take in carbon dioxide through small openings in their leaves called stomata, and then use the energy from sunlight to convert the carbon dioxide into sugars through a series of biochemical reactions.
How did the leaves obtain carbon dioxide?
At the stomata. Stomata are little pores on the surface that let Oxygen, Carbon Dioxide, as well as water in and out of the leaf.
What is carbon dioxide hydrogen and oxygen used for in leaves?
In leaves, carbon dioxide is used in photosynthesis to produce glucose, which serves as energy for the plant. Hydrogen is used in the synthesis of carbohydrates and other molecules, while oxygen is a byproduct of photosynthesis and is released into the atmosphere.
Where plants get carbon dioxide from?
from atmosphere
How do plants obtain carbon?
Plants obtain carbon dioxide from the air through tiny pores in their leaves called stomata. This carbon dioxide is used in photosynthesis to produce glucose, which serves as a source of energy for the plant.
The exchange of gases such as carbon dioxide and oxygen between the plant and the atmosphere?
is called respiration. Plants take in carbon dioxide from the atmosphere and release oxygen through small openings called stomata in their leaves. This process is vital for the plant's survival as it allows them to obtain the carbon dioxide needed for photosynthesis and release excess oxygen as a byproduct.
Does carbon dioxide molecules enter the Calvin from the atmosphere?
No, carbon dioxide molecules enter the Calvin cycle within the chloroplasts of plant cells. The stomata on the leaves allow carbon dioxide to diffuse into the leaf where it can be fixed into organic molecules during photosynthesis.
How do carbon reaches in leaves?
because leaves or plants absorb the carbon dioxide
