The limiting factors are oxygen concentration, carbon dioxide concentration and light intensity
Explanation:
All the factors have to be in efficient amounts for photosynthesis to take place. If one is inefficient, the process will be affected; just like a three legged stool, if you remove one leg, the chair won't be able to stand.
The major limiting factors for this experimental setup would be –
1) Light intensity – Photosynthesis can occur even at a low intensity light but to achieve the maximum efficiency and output the intensity of light must be high. This is the reason why plants photosynthesize the maximum during the brightest time of the day.
2) Concentration of carbon dioxide – Higher the concentration of carbon dioxide, higher is the rate of photosynthesis. Plants take carbon dioxide from the atmosphere.
3) Oxygen – The oxygen concentration must be favorable for photosynthesis up to its optimum level. Beyond the optimum oxygen level, the photosynthesis process inhibits.
A<em> fish ladder</em> is also known as fish steps, fish pass or fishway.
It is built around waterfalls, dams and locks.
The purpose of building a fish ladder is to<em> facilitate the natural migration of diadromous fishes.</em>
A fish ladder helps the fish to pass through the barriers by leaping up or swimming through the low steps of the ladder and reach into the water on the other side.
Since, without the fish ladder the barriers will not allow the migration of fishes, it is essential to be built around the dams, waterfalls and locks.
