Looking at the organisms associated with the lake, organize them into three trophic groups: producers, consumers, and decomposers. 4. Separate the consumers into three subcategories: herbivores, carnivores, and omnivores. 5. 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. 6. As the energy flows through each trophic level, how much energy is lost from the food chain as heat? 7. What happens to the number of organisms as they go up through the trophic levels? Explain why this…Describe five ways in detail, which you can reduce your ecological footprint to save our planet Earth.

He has unlimited access to water, six chickens, and a few bags of corn. He is considering his options for how to survive on the island until he is rescued. Draw a model of the food web and the trophic pyramid on the island for each of these three options. Option A: Feed all the corn to the chickens and eat their eggs. Trophic Pyramid Food Web Option B: Share the corn with the chickens. Eat their eggs, then eat the chickens when the corn runs out. Food Web Trophic Pyramid Option C: Eat the chickens first, then eat the corn. Food Web Trophic Pyramid3 Study this diagram of an ecosystem and answer the questions that follow, Figure 5.10 a What is an ecosystem? b Which number refers to a herbivore?

Explain what affeccts bringing predators in could have on the ecosystem. b. Which level of organisms is most susceptible to extinction. Please support your answer.Create a food web and Trophic Pyramid for an identified ecosystem. Only drawings Requirements: Identify your ecosystem (desert, rainforest, artic, etc) Food Web - 1. at least 15 organisms 2. 5 levels represented 3. Correct arrow movement 4.

- When hunting disrupts the balance in the food chain by removing all owls, there will be no predators on snakes, leading to their increase in numbers. Considering the scenario where the number of lost owls (4) is replaced by snakes, compute for energy units following in completing the table below. Trophic Levels No. Individuals in Each Trophic Level No. of Units Received from Trophic Level Above No. Units Used / Individual (Resp) No. Units Used in Trophic Level No. Units Remaining & Passed on to Next Trophic Level Mean No. Units Available per Individual in Trophic Level SUN +E = 6 1) Plants 30 2 2) Grasshopper 19 2 3) Frog 12 2 4) Snake 8 + 4 = 12 2 5) Owl 0 2You 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…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?
