Which interaction of a biotic and an abiotic factor can help stabilize a forest area in North Carolina? Mark only one oval.

• increased precipitation, reducing soil erosion in the area

• increased decaying organic material, adding nutrients to soil in the area

• decreased water salinity, reducing biodiversity of animals in the area

• decreased number of predators, allowing the number of prey to increase in the area
