North American Biomes Map with color key and questions for identifying biome types.

Explanation:
Let’s go through each question one by one using the MASTER KEY provided.

1. What type of biome has subsoil called “permafrost”?
→ Permafrost is permanently frozen ground, found in the Tundra.
✔ Answer: Tundra

2. What type of biome contains over half of all animal and plant species?
→ Tropical rainforests are the most biodiverse biomes on Earth.
✔ Answer: Tropical Rainforest

3. What type of biome receives less than 12 inches of rain per year?
→ Deserts are defined by very low precipitation (<12 inches/year).
✔ Answer: Desert

4. What type of biome is divided into “savannas” or “tropical dry”?
→ Grasslands include tropical grasslands like savannas and tropical dry forests (though sometimes grouped separately; but per key, *Grassland* matches this description). The key lists “Grassland” as an option, and savannas are a type of grassland/tropical grassland.
✔ Answer: Grassland

5. What type of biome has trees that drop their leaves in fall?
→ Deciduous forests lose leaves seasonally.
✔ Answer: Deciduous Forest

6. What type of biome is sometimes referred to as a “Taiga”?
→ Taiga is another name for the Boreal Forest (also called Coniferous Forest in some contexts). The key includes “Boreal Forest” and “Coniferous Forest” — but *Taiga* specifically = Boreal Forest. However, check the key: options include “Boreal Forest” and “Coniferous Forest”. In many curricula, Taiga = Boreal Forest = Coniferous Forest. But the key lists both separately. Since “Boreal Forest” is listed, and Taiga is the Russian word for boreal forest, the best match is Boreal Forest.
Wait — look again at the MASTER KEY list:
- Desert
- Deciduous Forest
- Coniferous Forest
- Tundra
- Tropical Rainforest
- Grassland
- Boreal Forest
So yes, “Boreal Forest” is explicit.
✔ Answer: Boreal Forest

7. What type of biome can be very hot in the day, but cold at night?
→ Deserts have large diurnal temperature swings (hot days, cold nights).
✔ Answer: Desert

8. What type of biome is on every continent except Antarctica?
→ Grasslands exist on every continent except Antarctica. (Deserts also exist on all except Antarctica? Actually, Antarctica has polar desert — but typically in school tasks, they say grasslands are on all continents *except* Antarctica. Let’s verify:
- Africa: savannas
- N. America: prairies
- S. America: pampas
- Eurasia: steppes
- Australia: rangelands
- Antarctica: no true grasslands (too cold/dry)
Yes, standard answer is Grassland.
✔ Answer: Grassland

9. What type of biome has three types: Arctic, Alpine, and Antarctic?
→ These are all types of Tundra (Arctic tundra, alpine tundra, Antarctic tundra).
✔ Answer: Tundra

10. What type of biome occurs near the equator and has lots of rainfall?
→ Tropical Rainforest is near the equator with high rainfall.
✔ Answer: Tropical Rainforest

Now, double-check all answers against the key options — all match available choices.

Final list:
1. Tundra
2. Tropical Rainforest
3. Desert
4. Grassland
5. Deciduous Forest
6. Boreal Forest
7. Desert
8. Grassland
9. Tundra
10. Tropical Rainforest

All consistent.

Final Answer:
1. Tundra
2. Tropical Rainforest
3. Desert
4. Grassland
5. Deciduous Forest
6. Boreal Forest
7. Desert
8. Grassland
9. Tundra
10. Tropical Rainforest
