(05.02 mc)the diagram below shows a marine food chain with the amount of energy available to each trophic level in parentheses. why does the amount of energy decrease as you move up the chain? a pyramid showing the marine food chain indicating the amount of energy available to each trophic level. at the top of the pyramid, level 5 shows tuna at an energy level of 0.5. trophic level 4 has mackerel at an energy level of 5, trophic level 3 has herring at an energy level of 50, followed by trophic level 2 with zooplankton at an energy level of 500 and phytoplankton at the bottom with an energy level of 2500.a: decomposers are using up the energy between each trophic level. b: individual organisms at the upper trophic levels require less energy to survive than those at the lower ones. c: producers use most of the energy before it can reach the upper levels. d: some energy is lost as heat or not consumed by organisms at the next trophic level.

The collared lizard is a species found in the desert southwest. male collared lizards show considerable color variation, ranging from brightly colored to a very dull pattern. your goal is to determine the function, if any, of male color patterns in collared lizards, using the scientific method. your tentative explanation is that male color plays a role in attracting females for mating purposes. you predict that females will preferentially choose brightly colored males over dull-colored ones. to test this prediction, you observed the interactions of female collared lizards with their male counterparts. you selected males that were the same age and size, and that differed only in their coloration pattern. you placed equal numbers of the two types of male lizards, bright and dull, in aquariums, along with one female lizard per aquarium. out of 350 aquariums observed, the female chose to mate with the brightly colored male 277 times, and the dull-colored male 70 times. in 3 instances, the females did not mate with either type. create a bar graph of your data, plotting the type of male (dull or brightly colored) on the x-axis. on the y-axis, plot the frequency with which each type of male was chosen by females. using this graph, answer the following question(s). is it reasonable to conclude (i.e., is it supported by the data) that female collared lizards prefer more brightly colored male lizards over dull-colored males?
