想請教一題生態的題目
Which of the following ecosystems would likely have a larger net primary
productivity/hectare?
(A) Open ocean because of the total biomass of photosynthetic autotrophs
(B) Grassland because of the small standing crop biomass that results from
consumption by herbivores and rapid decomposition
(C) Tropical rainforest because of the massive standing crop biomass and
species diversity.
(D) Cave due to the lack of photosynthetic autotrophs
(E) Tundra because of the incredibly rapid period of growth during the
summer season.
正確答案給的是 B
我想問的是 C
一般來說單位面積下的淨初級生產力不是應該是熱帶雨林最高嗎??
是答案錯了還是我有漏想什麼
謝謝
