Ecologists use similarities between ecosystems to classify them into broad categories called

• biomes.
• littoral zones.
• estuaries.
• benthic zones.

Why do shorter trees and plants that make up the understory in tropical rain forests have large, flat leaves?

• to shade themselves from excessive sunlight
• to create habitat for forest insects
• to offer protection from rain
• to allow maximum surface for light absorption (catch the most light)

In temperate rain forests, trees such as cedars and spruces, which do not lose their leaves at any time of year and produce pinecones, are called

• conifers.
• succulent.
• chaparral.
• deciduous.

Which biome is characterized by very low temperatures, little precipitation, and permafrost?

• desert
• temperate forest
• tundra
• tropical dry forest

Which two biomes have the LEAST precipitation?

• tropical rain forest and temperate grassland
• tropical savanna and tropical dry forest
• tundra and desert
• boreal forest and temperate woodland and shrubland

As shown in the figure, the climate zone that receives the most direct sunlight throughout the year is

• Tropical
• Temperate
• Polar
• Marine
