In an experiment, the hypothesis is if the wavelength of the light shining on a plant is shortened, the rate of photosynthesis is slowed down. if this experiment is performed, the independent variable

If this experiment is performed, the independent variable will be the wavelength of the light.

Explanation:

In a scientific experiment, there are two variables; the independent variable and the dependent variable. An independent variable can be described as a variable which either changes naturally or which is being changed by the scientists to study its effect on the dependent variable. The dependent variable can be described as the variable which depends on the independent variable.

Hence, in the following experiment, wavelength of the light shining would be the independent variable. The rate of photosynthesis will be the dependent variable.

for the points

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
