Answer:
C. A steep slope
Explanation:
Erosion is the removal of the top layer of the earth or the gathering of lose weathered materials from rock surfaces.
Agents of erosion are wind, water, glacier and gravity.
Along a very steep slope, erosion is highly rife and very prevalent to the extent that everything there is washed away to be deposited at the bottom of the slope or where gradient is more gentle.
On a steep slope, materials moves rapidly and gravity is very great. When these factors are coupled with the prevailing conditions in a place, little to no deposition occurs for soil formation.
· Abiotic factors are nonliving, such as temperature, sunlight, and soil in an ecosystem.
· Biotic factors are the living parts of an ecosystem, such as plants and animals.
Given the above, the biotic factor listed is evergreen trees in a coniferous forest.
The other options - soil, precipitation, and temperature - are abiotic.
