The population growth of which bacteria is more affected by growing conditions? Explain how you know. P. caudamum because its population decreased, which P. Aurelia stayed the same. Using the information provided in the graphs, make a prediction as to why the bacteria identified in part a is more affected by growing conditions than the other bacteria. P. Aurelia outcompeted P. caudamum for available resources. Interdependence in nature is illustrated by the transfer of energy through trophic levels. The diagram below depicts the transfer of energy in a food web of an Arctic lake located in Alaska. Identify an organism from each of the 5 trophic levels (producer, primary consumer, secondary consumer, teritiary consumer and decomposer) and explain how energy is obtained at each producer=phytoplankton; primary consumer=zooplankton; secondary consumer=grayling; tertiary consumer=lake trout; decomposer-snail. Describe the efficiency of energy transfer between trophic levels of this food web. Only 10% of energy is passed from one trophic level to the next; most energy is lost. Explain how the amount of energy available at each trophic affects the size of each population. The higher trophic levels have less energy and thus, smaller population sizes. If the cells in the dead terrestrial plant material that washed into the lake contained a commercially produced toxin, what would be the likely effects of this toxin on this food web? Explain. the toxin would spread throughout the food web and would become the most concentrated (biomagnification)at the tertiary consumer level. If all of the Sculpin in this ecosystem were removed, predict how it would impact the following and explain each prediction: The population of lake trout decrease
