What effect would a sudden decrease in light intensity have on the rate of photosynthesis of a particular plant?

Photosynthesis (the means of how a plant makes food to live) requires light, carbon dioxide, and water (or in some cases another electron donor compound). Deprive it of two of the three components and it can't occur and the plant will die and oxygen will not get produced. Stop enough of the plants/trees on the earth and then we eventually die.

∙ 14y agoIncreasing or decreasing the amount of light a plantreceives does affect the speed of the photosynthetic process; however remember that light (or sunlight) is only one of the three variables in the process. The amount of carbon dioxide and water available during photosynthesis also affect the speed and effectiveness of the process.

∙ 14y agothe plant will slowly begin to wither. the energy from photosynthesis is like food, without food they die.

Low levels = less photosynthesis

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 are some factors that affect photosynthesis?
The factor that will effect photosynthesis the most is light. Plants need light in order for photosynthesis to take place. Water, air, pH, and temperature will also effect photosynthesis.
Does light intensity or concentration of carbon have a greater impact on photosynthesis?
The light intensity has a little bit more effect. The amount of carbon dioxide is generally in excess of what is required for the photosynthesis. It would have to raise significantly above current levels to overtake the effect of light intensity. That is not to say carbon dioxide concentration isn't still very important. The carbon dioxide concentration also has a minor secondary effect by slightly expanding the tropical and temperate regions towards towards the poles when it is higher and shrinking them towards the equator when it drops - it has to be warm for photosynthetic plants to thrive.
What are the three things that effect the rate of photosynthesis?
The amount of sunlight, the amount of CO2,the amount of warmth and the amount of water all effect photosynthesis.The amount of sunlight, the amount of CO2,the amount of warmth and the amount of water all effect photosynthesis.
What affects the rate of photosynthesis?
The main variables which affect photosynthesis are light, CO2 concentration and temperature. You should be able to explain how each of these has their effect on the rate of photosynthesis. Although water is needed as a raw material for photosynthesis, if water is short, it will cause the plant to wilt (and thereby lose its ability to capture sunlight) long before it limits photosynthesis at the biochemical level. On a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg Mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis, though these are rarely covered in discussion of this topic.

What environmental factors directly influence photosynthesis?
well, temperate, light intensity, and weather effect the rate of photosynthesis
How will decreasing the amplitude of the sound waves from a TV affect its intensity?
Amplitude is intensity. It refers to the strength of a sound wave, which the human ear interprets as volume or loudness and if you decrease the amplitude you also decrease its intensity.

What are three factors that affect the rate of photosysthesis?
Amount of CO2 available, light intensity and temperature, all effect the rate of photosynthesis.
What is the most likely effect a decrease of plant life in the biosphere would have on the atmosphere?
As a byproduct of photosynthesis, plants produce oxygen. A decrease in plants would mean a decrease in the amount of oxygen being released into the atmosphere, although such a decrease would have to be large in order to produce a noticeable effect.
What is the effect of sunlight on plants?
At first, sunlight causes an increase in photosynthesis. At some point, photosynthesis stops increasing with increasing sunlight. At this point, the chlorophyll molecules are saturated. Further increases in sunlight cause a decrease in photosynthesis as chlorophyll molecules are destroyed.

For maximum photosynthesis increased light intensity has greater effect than increased leaf surface area?
false Edited answer: In case light is limiting factor in the given situation.
What is the possible explanation of the shape of the curve showing the effect of increasing light intensity on the rate of photosynthesis?
It would show a possertive correlation, there is a better word but I can't remember it, sorry
What effect do pesticides have on photosynthesis and respiration?
Pesticides have adverse effect on photosynthesis and respiration on host pants.
