Which biome pairs are matched correctly with their key features?

• Coniferous forests → fir cones; Shrublands → rocky terrain; Grasslands → tall grasses; Tundra → snowy landscape

• Coniferous forests → sandy soil; Shrublands → desert plants; Grasslands → evergreen trees; Tundra → warm summers

• Coniferous forests → cacti; Shrublands → glaciers; Grasslands → shrubs; Tundra → tropical trees

• Coniferous forests → palm trees; Shrublands → corals; Grasslands → moss; Tundra → vines

Which statement correctly describes coniferous forests?

• They have needle-shaped leaves and cones, and occur at lower latitudes with year-round rainfall.

• They have broad leaves and lose them in winter.

• They are deserts with very little rainfall.

• They are grasslands with only seasonal rain.

What effect do low temperatures have on plants?

• They slow evaporation, reducing water loss.

• They increase evaporation, drying out plants faster.

• They stop photosynthesis completely.

• They make plants produce cones and needles.
