Scientists designed an experiment to learn about the functioning of the hydrologic cycle and the phosphorus cyde
did not disturb the other plot. They were able to accurately measure the amount of water that flowed out of the
in a forest. Using two areas of the same size and geologic features, they cut all the trees down from one plot and
two plots as well as measure the amounts of phosphorus found in the runoff.
(a) Describe what the differences would be in the volume of water running off the two plots and give ONE
(b) Describe the differences in the levels of phosphate found in the runoff of the two plots. Assume that both

(c) Describe ONE negative effect that might occur in a stream that receives the runoff water and sediment.
(d) When a tropical rain forest is cut down and used as farmland, the fertility of the soil only lasts a few years.
plots started off with the same amount of phosphorus in the soil.
Give an explanation as to why there is little organic matter in rain forest soil and what would happen to the
material after deforestation.

It is due to faster decaying of dead plants and recycling of nutrients by the new plants.

Why there is little organic matter in rain forest soil?

The soil of rain forest soil contains less organic matter than other forest soils because the warm humid conditions encourage faster decaying of dead plants and recycling of nutrients by the new plants.

So we can conclude that faster decaying of dead plants and recycling of nutrients by the new plants is the reason for low content of organic matter.
