Which of the following is not the effect of C3 and C4 cycle in hot and dry climates ?

#Section 5: Applied Ecology & Evolution
  1. elevated temperatures limit the rate of photosynthetic CO2 assimilation in C3 plants by decreasing the solubility of CO2
  2. In C4 plants warm climates decrease the levels of CO2, but the low concentrations of cytosolic HCO3 − saturate PEP Case because the affinity of the enzyme for its substrate is sufficiently high
  3. The optimal photosynthetic efficiency of C3 species generally occurs at temperatures lower than for C4 species
  4. C4 species become less abundant in the tropics and subtropics and more abundant when latitudes depart from the equator

The population density of a particular insect species was determined to be 15,000 adults per hectare in the summer of 1996, 21,000 adults per hectare in the summer of 1997, and 29,400 adults per hectare in the summer of 1998. Based on these population estimates, what is your estimate of λ, the annual rate of geometric growth?
