The ambient temperature exerts an important influence over Ω and the concentrations of CO2 and O2 around the active site of rubisco. Warmer environments have the effect of;  Find the incorrect one?

#Unit 6. System Physiology – Plant
  1. increasing the oxygenase activity of rubisco more than the carboxylase activity. The greater increase of KC for CO2 than of KO for O2 diminishes the W of rubisco
  2. The increase of [O2]/[CO2] decreases the vC/vO ratio; that is, the oxygenase activity of rubisco prevails over the carboxylase activity
  3. Increasing the stomatal aperture to conserve water, the stomatal closure the uptake of atmospheric CO2, thereby decreasing CO2 at the active site of rubisco

  4. warmer environments significantly limit the efficiency of photosynthetic carbon assimilation because the progressive increase in temperature tilts the balance away from photosynthesis (carboxylation) and toward photorespiration (oxygenation)

Ecologist have proposed following explanation to lead maximize biodiversity at tropic.

A. Higher productivity in the tropics allows for more species present

 B. Old communities have greater species than younger community

 C. Natural enemies such as predators and parasite limit competition in the tropics, which allows more species to coexist

D. Very less intensity of disturbances in the tropics promote high succession diversity
