Section 4-3 Assessment
1. The major biomes are Tropical rain forest, tropical dry forest, tropical savanna,
desert, temperate grassland, temperate woodland and shrubland, temperate forest,
northwestern coniferous forest, boreal forest, and tundra. The characteristics are
listed between pages 100-105.
2. Biomes are classified by their climate, which is determined by precipitation and
temperature, and by the community of organisms that live there.
3. Tropical rain forests have higher temperatures and more rainfall annually than do
tropical dry forests.
4. Animals found in mountain ranges must be adapted to cooler, wetter conditions
that are found there.
5. Tundra animals need to be well insulated with thick coats of fur/hair or layers of
Section 4-4 Assessment
1. Depth, flow, temperature and chemistry of overlying water
2. They are alike in that the water contains oxygen and nutrients. They are different
in that the water in a flowing-water ecosystem moves rapidly near the source and
slows near the mouth. Water in a standing-water ecosystem has little net flow but
circulates within the system.
3. Photic zone, aphotic zone, intertidal zone, coastal zone, open ocean, benthic zone
