How do autotrophs obtain CO2 and N2 to make their food?
CO2 is absorbed via stomata while N2 is absorbed from soil in form of ammonia or nitrates etc. via root hairs .
How does oxygen enter the human body?
oxygen (O2) enters the body via respiration (breathing) it enters small pouches in the lungs called alveoli. these alveoli are surrounded by tiny blood vessels called capillaries. there is an exchange at these alveoli, carbon dioxide (CO2) exits the blood and O2 enters the blood. this freshly oxygenated blood is now returned via the pulmonary vein to the Left side of the heart. the left ventricle pumps blood to the body. as the blood vessels get smaller they again form capillaries. there is another exchange of gasses, O2 is transferred out to the cells and CO2 (the waste product from cellular metabolism) is transferred to the blood. the Deoxygenated blood is then returned via the venous system to the right side of the heart. the deoxygenated blood is pumped back to the lungs and the alveoli via the pulmonary artery. and then the whole cycle starts over again.hope this helps :)
How is co2 removed from the body?
We find that carbon dioxide is removed from the body via what is called gas exchange in the lungs. When we inhale, air is drawn into the lungs, and the alveoli in the lungs are the sites where gas exchange takes place. Carbon dioxide exits the blood, and oxygen enters. When we exhale, the carbon dioxide is carried out of the body, and the process is repeated with another breath.
How do plants get the carbon dioxide they need during photosynthesis?
That's easy, if you're talking about from which part of the plant they inhale it with, that would be the leaf, or pine needle. If you're asking how, the leaf simply has hundreds of tiny, microscopic holes in which the plant itself uses to take in CO2. (Carbon Dioxide)
Can pass through stomata?
Yes most gases do.
CO2 enters and 02 escapes from a leaf via?
I think that I am riegh
How does carbon dioxide and water reach the chloroplast in leaves?
The chloroplasts in the leaves absorb the light directly from the sun. The carbon dioxide goes into the leaves through the stomata (tiny holes on the bottom of a leaf) and is diffused through the rest of the cells. The water is absorbed by the roots then carried by the xylem up to the leaf and the cells in the leaf.
How does oxygen enter the leaf?
Oxygen moves through leafy plants through the "stoma, pleural: stomata". They are small pores in the leaf that can open and close to allow gas exchange. However, most plants exhale oxygen (O2) and inhale carbon dioxide (CO2), so oxygen is generally leaving a plant.
How does oxygen enters to our body?
Oxygen enters via the lungs.
What two types of cells are involved in the absorption of co2 and release of h2o from a leaf?
Absorption of CO2 occurs via photosynthesis; release of H2O is respiration: both occur in plant cells - the former only in light conditions and the latter continuously.
What cools lava?
The heat escapes into the atmosphere via air or water.
Where does carbon dioxide enter in a leaf via holes?
the leaf!
Which class of nutrients enters the body via the lymph?
lipids

Does blood enter the lungs via the pulmonary artery?
Yes, the blood enters the lungs via pulmunery artery
Oxygented blood enters which side of the heart?
Oxygenated blood enters the left side of the heart (atria) via the pulmonary veins
