explain why a continuous increase in carbon dioxide levels will not cause the rate of photosynthesis to increase continuously?​
Zepler [3.9K]

Answer:

An increase in the amount of CO2 well increase the rate of photosynthesis, Carbon dioxide concentration will directly affect the rate of photosynthesis as it is used in the photosynthesis reaction.Increased amount of CO2 will increase the rate of photosynthesis to a certain limit, after which a further increase in its amount will no longer increase the rate any further. This is when the other factors necessary for photosynthesis, such as light, become "limiting reactants"; that is, those other factors also need to increase to bring about a further increase in the rate.

six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen

An increase in the amount of water leads to the increase in the amount of photosynthesis

The amount of water available to the plant will affect the rate of photosynthesis. If the plant does not have enough water, the plant's stomata will shut and the plant will be deprived of CO², and thus lower photosynthesis rate.

An increase in the amount of light well increase the amount of photosynthesis, if the light intensity increases the rate of the reaction will increase at a proportional rate until a certain level is reached, the rate of increases will then go down.

Other factors affecting the rate of photosynthesis :

1. Temperature

2. The availability of nutrients

Advantages of constant body temperaure
Leya [2.2K]
Proteins function optimally at a specific temperature. So if you get too hot or too cold, biochemical reactions in your body start to function less well. If the situation becomes extreme enough, they can cease to function well enough to sustain life. 

Warm-blooded animals have an advantage over cold-blooded ones in that their bodies automatically try to maintain the optimal termperature for things in their bodies to function. Cold-blooded animals depend on the environmental temperature to do this for them. That's why reptiles are very sluggish when they're cold, but will "wake up" when they get warm. 

The cost to this benefit is that metabolically, warm-blooded animals require a lot more fuel to run their bodies. It's very energy-intensive to maintain a constant body temperature. Cold-blooded animals require far less fuel than warm-blooded ones relative to their size. 

The way that proteins operate in a specific temperature is also true of the pH in your body which is also very tightly maintained.
