Identify the biomes that are likely to be shown in the graph.
What is Biome A and Biome B?
A. Rainforest Tundra
B. Rainforest Savanna
C. Desert Tundra
D. Tundra Savanna
参考答案: D
本题详细解析:
The net primary productivity of the tundra and desert biomes are jzuq,l : 7 5t3bd,6lrcrpchlbh1 +gg0relatively lower than the rainforest and savanna biomes. The biomass of herbivores is therefore lo03+lhuc6,bdltz, 17 5 r gqcblg:jhrp wer in the tundra and desert biomes as compared to the savanna and rainforest biomes.
Option D is correct, since the biomes at the lower end of the graph have low productivity and lower biomass of herbivores (tundra) and the biomes at the higher end have higher productivity and higher biomass of herbivores (savanna).
