Question

Other than changes in precipitation patterns, what other factors might change the amountof water available to a plant (NAME AT LEAST 2)? How might some of those factors change as a result of climate change? HINT: Think back to the unit, Buffalo of the Serengeti, "other factors" can be considered as "limiting factors". What "other factors" could limit or alter water availability?

Answer 1

In this case, we have that CO2 has an effect on water availability, in the lecture is mentioned climate change as a reason for droughts and water stress, nonetheless, it can cause the contrary effect an excessive rain that will cause floods and drawn crops. Another effect is that the greenhouse effect generated by CO2 increases heat and in consequence excessive evapotranspiration (loss of stomatic control) leading to plant wilting. What's more evaporation from the soil can increase leading to a change in hydric potential in the plant and finally wilting.
