Final answer:
Topography can influence soil erosion and nutrient accessibility for plants and animals.
The correct option is A.
Step-by-step explanation:
Topography, or the regional surface features, can have a significant influence on soil characteristics. For example, topography affects erosion by influencing water runoff, which can strip away parent material and affect plant growth. Soils in steep areas are more prone to erosion and may be thinner than soils in relatively flat or level areas.
Additionally, topography can affect the availability of soil nutrients to plants and animals. Steep slopes can make it more difficult for plants and animals to access soil nutrients, while flatter areas may have more easily accessible nutrients.
The correct option is A.
