- Beavers are powerful ecological engineers. When they dam flowing streams they can create ponds and wetlands. Select all of statements indicating the way that beavers change energy flow and element cycling by damming streams. CLIMASE ATAPLAR FORM Beavers have no effects on energy flow through the brown and green food web Beaver dams indirectly increase net primary productivity by creating wetlands and ponds Beavers indirectly reduce secondary productivity Beavers indirectly decrease primary productivity by turning streams into ponds or wetlands Beavers indirectly cause greater releases of carbon to the atmosphere by damning streams Beavers indirectly increase energy flow through the green and brown food wegs Beavers indirectly increase net secondary productivity Beavers indirectly increase carbon storage in organic matterRain (cm) 60 50 40 30 20 10 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2. An ecosystem has an average of 50 cm of rain per year. Look at the rainfall graph over an 11 year period of lower than average rainfall in this ecosystem, predict how the biotic factors within this ecosystem would respond. Make sure to describe how eventually all trophic levels would be affected. Be sure to explain your reasoning Answer: Type your answer here.In your own case study, describe and illustrate how changes in an organismal population can have unintended effects on trophic levels or ecosystems. Identify the organisms and nutrients that are present in your trophic pyramid. Describe the normal flow of your trophic cascade along with whether removal or introduction of the organism has a positive or negative effect on other organisms or nutrient levels within an ecosystem.

- A conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below. Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction. Question: Why does the organism’s interaction appear in an oscillating pattern? What does it suggest?Each of the following terms represents a type of economic value we place on the services we get from an ecosystem except one. Which one is NOT an economic value? O O 0 O Provisioning Indirect Bequest Existence DirectA conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below.

- You will be examining the relationship among organisms inhabiting a small lake. Examine the “Lake Inhabitants” sheet for information about the organisms found in the lake. What biotic and abiotic factors will affect the aquatic plants in the lake? What biotic and abiotic factors will affect the bluegill in the lake? Looking at the organisms associated with the lake, organize them into three trophic groups: producers, consumers, and decomposers. Separate the consumers into three subcategories: herbivores, carnivores, and omnivores. Create 3 different food chains found within the lake. Food chain #1 should contain 3 organisms, food chain #2 should contain 4 organisms, and food chain # 3 should contain 5 organisms. The arrows should point in the direction the energy is flowing through the food chain. You can either use the “>” as your arrow or the Insert Symbol function to insert an arrow into your food chains. As the energy flows through each trophic…Using your knowledge of limiting factors in terrestrial & aquatic ecosystems and our content in this Module, write paragraph to explain WHY the following statement is true. 4-5 descriptive sentences are expected; be sure to support your points adequately.
