Ответ:
The soil is made up of layers, called horizons, which are parallel to soil crust. These horizons are from top to bottom:
O - contains organic matter.
A - contains organic matter mixed with mineral matter.
B - contains accumulated mineral or organic compounds.
C - consists of parental material.
R - consists of bedrock, masses of hard rock.
Thus, through the process of elimination:
a. b horizon is not rockier that the c horizon because c horizon consists of parental material.
b. a horizon is richer in humus because it consists of more organic and mineral material than b horizon.
d. c horizon is thicker than b horizon.
This leaves choice c. less nutrient rich than the a horizon. A horizon is richer in organic and mineral material than b horizon.

Explanation:
This glucose derivative is in fact the main building block of cell walls in not only arthropods (including the shrimp), but also fungi and insects, and also has a structural function in the scales of fish. The most similar commonly-known substance in terms of function is keratin, which makes up our hair and nails.
