The organisms found there not only serve as food but increasingly are the sources of new to fight diseases and infections such as coastal pollution andThe population of Desert Paradise (DP; a fictitious town) hasbeen doubling every 7 years. Most of the new inhabitants are“snowbirds,” people escaping the cold winters of northerlylatitudes. There are no permanent streams or lakes anywherenear DP. In fact, the only standing water occurs in the ponds ofthe many golf courses that have been built recently. The water inthese ponds needs to be replenished almost constantly, or theponds will dry up. The golf courses and yards of the suburbanstyle developments of DP all have lawns of green grass. DP hasbeen growing on a flat, sediment-filled basin between two smallmountain ranges. Much of the water supply of DP comes fromwells. What do you predict will happen to the water table of thearea in coming years, and how might the land surface change asa consequence? Might you suggest a policy to the residents ofDP that could slow the process of change?

Bcologists, including aquatic biologists, use the range of tolerance to monitor the number of different populations residing in the area. m order to do so they use statistical models. Create a graph displaying on the x-axis the ranges of abiotic conditions such as temperature to study the population of rainbow trout in the area ( use the launch model as an example), Label each interval with temperature range and condition. What Causing Stress in Rainbow Trout Population The optimal range is the amount of an abiotic factor that produces the highest possible population. For water temperature, this would be about 6-10°C.
