Answer to Question 1

The more daisies, the more sunlight reflects off their white petals, the less sunlight absorbed, and finally the cooler the surface temperature. In sum, as daisy coverage increases, temperature decreases. The stable equilibrium state is below the growth optimum.

Answer to Question 2

The reflectivity of a surface (expressed as a decimal fraction or percent) is called the surface albedo. The reflectivity of an entire planet is called the planetary albedo. Increased albedo causes a decrease in temperature (a negative coupling).
