In 1996 a new disease called devil facial tumor disease ( DF^ prime ) appeared in the wild Tasmanian devil population. DFTD can spread from one animal to another and causes the death of most affected animalsThe impact of DFTD on the Tasmanian devil population has resulted in a decrease in the total population of more than 85% over the last two decades . (a) Describe the process that maintained a stable Tasmanian devil population size before the appearance of DFTD in 1996.

Describe the change in phase and temperature as water moves from the oceans to the atmosphere and then returns to earth again as rain. a) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature decreases b) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature increases c) evaporation : temperature decreases; condensation : temperature decreases; precipitation (rain) : temperature decreases d) evaporation : temperature increases; condensation : temperature increases; precipitation (rain) : temperature decreases
