Which interaction of a biotic and an abiotic factor can help stabilize a forest area in North Carolina?

• Increase precipitation, reducing soil erosion in the area

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

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

• decrease number of predators, allow the number of prey to increase in the area

How does distance from the equator affect a location's climate?

• Closer to the equator, a climate is likely to have higher temperatures and more precipitation

• Closer to the equator, a climate is likely to have lower temperatures and less precipitation

• Closer to the equator, a climate is likely to have a milder temperature and more moderate precipitation

• Closer to the equator, a climate is likely to have lower temperatures and more precipitation
