Choose an example of an organism from those listed in Figure 1: Meadow Ecosystem Energy Pyramid for each of the energy roles listed in Chart 1, “Energy Roles of an Ecosystem”. Justify your choice using information that you have learned about the role and functions of organisms in an ecosystem. Chart 1: Energy Roles in an Ecosystem Ecological Role Example Justification Producer Consumer Decomposer 17. Explain why the amount of energy changes as you move up the energy pyramid. Use examples from Figure 1, “Meadow Ecosystem Energy Pyramid,” to support your response. The amount of energy c___________________ as you move up the energy pyramid. This occurs because producers get their energy from the s____________. Producers don’t eat other organisms to get their energy. As you go up the energy pyramid, there are consumers. Consumers e__________ other organisms to get their energy. All organisms use 90% of their energy to live and store ____% in their bodies (in fat and muscle). When consumers eat other organisms for food, they are only getting 10% of e______________ that organism had. For examples, producers like the maple trees, grass and s____________, have 100% energy. But when the rabbits, grasshoppers and s_______________, eat the producers, they are only getting ______% of the producers energy that was stored in their bodies. When the snakes, owls and f__________, eat the primary consumers, they are getting only 10% of the energy. This continues as you go up the energy p___________________. 6 Complete the following questions using Figure 2: Oregon Ridge Ecosystem. Figure 2: Oregon Ridge Ecosystem. 18. Explain how the ecosystem in figure 2 would be affected if the maple tress were to become infected with a disease and the population was cut in half. Use prior knowledge to support your response. All organisms are interconnected with each other. If one population c__________________, all the populations are affected. If maple trees were affected by a l_____________________ factor, disease, then squirrels, r____________________ and grasshopper populations would decrease because they eat maple trees. Also, organisms such as foxes, snakes and owls would also d____________________a little because they consume squirrels and rabbits. 7 19. Figure 2: Oregon Ridge Ecosystem shows interactions between various organisms in the Oregon ridge Ecosystem. First, construct a food chain showing the flow of energy in the Oregon Ridge Ecosystem. Then write a papagraph which describes a name of a producer in your food web, the role of the producer in the food chain, what would happen if the population of the producer decreased and vocabulary evidence to support your answer. Finally, identify the name of a consumer and decomposer in your food chain. _________________ ________________ ________________ An example of a producer in the Oregon _____________ Ecosystem is _____________________. Producers play a big role in an ecosystem. Producers are plants that make their own e_____________________ through photosynthesis. They are the basis for an ecosystem. Primary c______________________ eat producers. Without producers, no other organisms would survive. If the population of the producer decreased, many other organisms would be affected. A limiting factor is a variable that can increase or decrease a p___________________________. If producers _______________________, the availability of resources (f___________) would decrease, causing consumers and decomposers to be affected. If the producer population decreased, consumer population would ______________________________because consumers eat the producers. If the producer population decreased, decomposer populations may increase because decomposers would have more d_____________________ consumers to eat. If the producer population decreased, decomposer populations may decrease because decomposers would have less p_______________________ to eat. The name of a consumer in the ____________________ Ridge Ecosystem is ____________________. The name of a decomposer in the Oregon Ridge __________________ is ____________________. 8 20. Using Figure 3: Food Web, identify two organisms that need grass to survive. Then explain why the organisms may compete with one another for the grass resource. Include in your explanation, the concept of limiting factors. Finally, explain what may happen to 3 other organisms if the population of rabbits increases. Figure 3: Food web wolves Grass rabbits coyotes Bison eagles ______________________ and ____________________ need grass to survive because they are consumers and eat the producer grass. Bison and rabbits may c_______________ for grass because it is a limited resource. A l_____________ f____________ is any variable that can i__________________ or decrease a population (examples include: availability of resources, disease, competition, human impact, predation). Availability of r_______________ such as grass is a limiting factor for populations. If there isn’t enough grass, then populations of bison and/or rabbits will ______________________. If one population changes, then all the other populations will be affected. For example • If the populations of rabbits increases, then grasses will _________________ because rabbits eat the grass. • If the populations of rabbits increases, then bison will ___________________ because they will have less grass to eat. • If the populations of rabbits increases, then the populations of wolves, coyotes and eagles will ________________ because they are predators and eat rabbits. 9
