Which is a biotic factor that could affect an ecosystem?

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

• 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

Which biome has the MOST vegetation?

• desert

• forest

• grassland

• tundra

One biome includes bearberry, a short plant with small, waxy leaves, shallow roots, and flowers that bloom quickly in the short growing season. Another biome includes tall grasses that can survive fires due to roots that extend 6 to 7 meters deep during the long growing season. What is MOST likely true about the two biomes?

• They have the same temperature range but different rainfall ranges.

• They have the same temperature range and the same rainfall range.

• They are at different latitudes but have the same temperature range.

• They are at different latitudes and have different temperature ranges.

Sweet potatoes grow best in sandy, well-drained soil. In which North Carolina ecological region would you MOST likely grow sweet potatoes?

• piedmont

• tidewater

• coastal plain

• mountain

Many birds live in mountainous temperate forest ecosystems. Above the tree line on mountains, however, the ecosystems change. Few birds are found there. Many factors contribute to the lower number of birds seen above a mountain’s tree line. Which of these factors is abiotic?

• limited food

• no trees for shelter

• frequent high winds

• high-flying predators

Biomes include both biotic and abiotic elements. Which set includes BOTH biotic and abiotic elements of an estuary?

• cordgrass, water salinity, great blue herons

• ospreys, oysters, black needle rush

• silt, air temperature, tidal pattern

• periwinkles, bats, egrets
