: 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

: summer season.
: 正确答案给的是 B
: 我想问的是 C
: 一般来说单位面积下的净初级生产力不是应该是热带雨林最高吗??
: 是答案错了还是我有漏想什麽
: 谢谢
