Adjacent soils that show differing profile characteristics reflecting the influence of local topography are called toposequences. As a general rule, soil profiles on the convex upper slopes in a toposequence are more shallow and have less distinct subsurface horizons than soils at the summit or on lower, concave-upward slopes. Organic matter content tends to increase from the summit down to the...
animals called decomposers do exactly what their name implies, they decompose organic material. these include worms, pill bugs, and an assortment of things to tiny to see with the naked eye. I believe this is the answer to your question.
how do soil form and what are the soil profile?
Considering that these horizons are in order from top soil to unconsolidated bedrock, usually, a soil profile will have the Organic horizon, the A horizon, the B horizon, the C horizon, and the R horizon.
The A horizon in soil is typically made up of mineral and organic material. In some instances the A horizon is only 2 to 3 inches deep, although it can be much deeper if the land has been plowed.
Hi
The soil profile in a rain forest would be very rich in humus (decayed organic matter). The soil profile in a desert would be almost totally devoid of any organic matter.
called a population pyramid. It consists of two bar graphs, one representing the male population and the other representing the female population, with age groups typically shown on the x-axis and the percentage or number of individuals in each age group on the y-axis. The shape of the pyramid can provide insights into the population's characteristics, such as whether it is growing rapidly or aging.

go to edit profile...put the letter Z and save profile!!
The soil profile is different because the desert soil profile has contained a little organic mater also are thinner than soils in wetter climates.Prairie soils have thick, dark A horizons because the grasses that grow there contribute lots of organic matter. Temperate forest soils have thinner A horizons than prairie soils do.
