Nitrogen
" " is taken in as nitrates and is needed to form proteins and chlorophyll. Without nitrogen the plant's leaves turn yellow and the plant shows poor growth.

Turning something off means that it stops using energy immediately, and the meter in your house stops clocking up the energy that it uses. At the end of the billing period the bill will be lower. If you turn off a 100 watt appliance for 10 hours, that saves one unit. If you turn off a 3 kw clothes drier for 20 minutes, that also saves one unit.

Leaves change color because the trunk of the tree stops sending nutrients and water and other chemicals to the leaves. In the winder, the tree keeps all the nutrients inside and doesn't have the energy to keep feeding the leaves, so they change color and die and fall off. Trees with leaves that do not change color just means that they don't have this process and are most likely in a warmer climate or survive much better in cold
The time when the human female stops producing eggs. The menstrual cycle stops.
It stops at about 0.12 seconds.
Deciduous leaves turn red and yellow in the fall due to the breakdown of chlorophyll, which reveals other pigments present in the leaves such as carotenoids (yellow) and anthocyanins (red). As the days get shorter and temperatures drop, the tree stops producing chlorophyll, allowing these other pigments to show through.
Open the oxygen tank valve completely until it stops turning. Be sure not to force the valve past the point where it stops turning to prevent damage.
Stops leaves from getting into the pool.
In the fall when the plant stops making chlorophyll.
Light never stops if GOD or yourself leaves it on..........It also stops when GOD or yourself turns it off.....................
Slows down and eventurally stops. That is why in the fall leaves turn yellow and other pretty shades and eventurally fall off the tree because they are not producing and sugar (glucose) for the tree so they are no longer needed

Henry Grimm barges in on them and then Puck leaves.
You are not in Mineral Town. You are in Forget-Me-Not Valley. But you will never be allowed to leave the valley and enter the town. Jakie always stops you.
The vibrant colors of red, orange, yellow, brown, and purple in fall leaves result from the breakdown of chlorophyll, the green pigment responsible for photosynthesis. As days shorten and temperatures drop, chlorophyll production slows and eventually stops, revealing other pigments in the leaves. Carotenoids produce yellow and orange hues, while anthocyanins create red and purple shades, often formed in response to sunlight and cooler temperatures. The combination of these pigments, along with the remaining chlorophyll, creates the stunning fall foliage we admire.
it stops you from getting to many r.p.ms turning your engine and over heating it.
I don't know the scientific equation, but I do know that the tree withdraws it's sugars from the leaves, during the autumn and winter to make sure that there is enough for the main tree. The withdrawal of the sugars is a physical action, but it is a chemical one as well. The chlorophyll that was made thru the sunlight on the leaves for photosynthesis. This stops when the weather turns colder and there is less sunlight causing the leaves lessen the amount to chlorophyll they can make, signaling to the tree to cut off the sugar supply to the leaves. I'd say it's both. Also, You have witnessed a spectacular chemical change if you have seen the leaves on a tree change from green to bright yellow, red, or orange. But, it is not a change from a green pigment to a red pigment, as you might think. Pigments are chemicals that give leaves their color. In autumn, however, changes in temperature and rainfall amounts cause trees to stop producing chlorophyll. The chlorophyll already in the leaves undergoes a chemical change into colorless chemicals.Where do the bright fall colors come from? The pigments that produce fall colors have been present in the leaves all along. However, in the summer, chlorophyll is present in large enough amounts to mask these pigments. In the fall, when chlorophyll production stops, the bright pigments become visible.
