- Science Name: Date: Class: Range of Tolerance Data Analysis One of the responsibilities of an aquatic biologist is to make sure that the abiotic factors stay wiumh the acceptable ranges for the optimal help for the Species within the local ecosystem. 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. Label this area on the graph. 1. 2. The zone of physiologic stress occurs when an abiotic factor exists at levels that are…Look at the pictures below. One picture showe a rainforost environment, and the other shows a dooort onvironment. Many rainforost plants have large, fat leaves. Many dosert plants have small neodio-iko loavos. What is the best reason for this difforence? (SC.SL.17.1) P O The plants are different ages. O The plants in the desert do not reproduce.

O The environmental conditions or geographic area where a species does not live.Why would a polar bear be unable to migrate from the North Pole to the South Poles? As it approached the equator it would overheat because it is adapted for cold climates, not warm ones. It would be unable to navigate across any bodies of water because they are too far across to transverse. O It would be unlikely to have enough insulation on its body to survive the trip. O There would be very few sources of food as it made the long trek across the globe. EBWhy can many different physiological groups of organisms livein a single habitat?
