Soil Profile is the Condition of the Soil in an Area.
And as it happens, the soil profile of the Tropical Rainforest is surprisingly bad. One may think that god soil would be required to aid so many plants, but it's really that all those plants are making the soil profile less and less quality. For one, those plants are sucking up nutrients, and for the second thing, all the rain that comes washes away nutrients and minerals from the topsoil (not to mention that the topsoil is only around 2 inches!).
Succession Explains how a Community got to where it is from where it was
Primary succession goes from land stripped of resources to a stable community. Primary succession is near to always caused by natural disasters.
In the rainforest, this occurs when there are disasterous floods and downpours that strip the land of plants, nutrients, and habitats. The area then begins to grow small bacteria as it creates new resources, then mosses, then small plants. And at this point, succession allows the community to be stabile and healthy.
Secondary succession happens on a smaller level and is done by destroying an area. In the tropical rainforest, one example of secondary succession would be when loggers come through and chop down trees, and then the land is used for farming. After an amount of time, the plants deplete the soil of nutrients. But soon after, those plants die (and stop sucking up nutrients) and the nutrients come back and the process speeds up in a similar fashion. Secondsary succession occurs much faster than primary succession due to it not being completely destroyed, but just lacking in resources.
