What biological macromolecule is made up of monomers like the one shown below?
fat
carbohydrate
protein
nucleic acid

"Carbohydrate".

Explanation:

The given figure explains the structure of Carbohydrate, as chemical structure depicts 6 atoms of carbon, 12 hydrogen and 6 atoms of oxygen, that makes C6H12O6 (Glucose).

The given chemical structure is glucose, having hexose sugar (6 carbon atoms), enclosed in pyran ring forming dextrose sugar.

Glucose structures are found in various forms and mirror images as D-Glucose and L-Glucose, which are formed due to mutarotations.  

So, the given picture represents the monomer (glucose) which form another polysaccharide (carbohydrate).

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
