C. It is decreased by a factor of 3.
A) Salt, because salt can easily dissolve in water. Oil would not dissolve or evaporate in water (think of an oil spill - does that oil dissappear?). Aluminum foil would definitely not dissolve in water, so it is not soluble.
Both of the lizards have adapted by having their skin the same colour as their habitat so they could camouflage into the environment and not be spotted by predators.
the rabbit population would decrease as the rabbits would be unfamiliar with the new predators way of hunting so they wouldn't have adapted to be able to get away from the new predator
Energy transferred per second in given area:
8000 x 3.9 / 10000
Energy transferred = 3.12 J
Using Planck's equation:
E = nhc/λ
n = (3.12 x 510 x 10⁻⁹) / (3 x 10⁸ x 6.63 x 10⁻³⁴)
n = 8 x 10¹⁸ photons
