This form of a food web begins with waste materials and theremains of dead organisms.a. aquaticb. detritalc. grazingd. atmospherice. geologicalThe cyanobacteria in Lake Erie would best be described as .a. decomposersb. tertiary consumersc. primary producersd. heterotrophse. secondary consumersScience 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…
