: 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
