🌳Ecology Test

Which biome has the MOST vegetation?

• Desert

• Forest

• Grassland

• Tundra

Plants have adapted to survive in a desert biome. Some of these adaptations are described below. Select all of the adaptations to biotic factors in a plant's desert biome.

• Spines protect plants from consumers.

• Flowers open at night for pollination by bats.

• Needles lose less water than broad leaves in high temperatures.

• Wide root structures help plants soak up water in rare rainstorms.

The table contains information about 4 global biomes.

Select the two biomes that are found in temperate latitudes

• Biome 1

• Biome 2

• Biome 3

• Biome 4

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

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
