List the variety of ways that species have developed to escape their predators (at least 4 ways). 3. Design a food web for humans. (it should be more than 10 species)3 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?

A primary consumer ii. Microscopic autotrophs iii. A predator that is a secondary consumer iv. A predator that is a quaternary consumer b. Construct TWO food chains based on this food web. At least one of them must feature FOUR organisms. Each of the food chains should have a different producer. c. EXPLAIN why food chains are unlikely to contain more than 4 organisms.Of the total amount of energy that passes from one trophic level toanother, about 10% isa. respired and becomes heat.b. passed out as feces or urine.c. stored as body tissue.d. recycled to autotrophs.e. All of these are correctWhat biotic and abiotic factors will affect the aquatic plants in the lake? 2. What biotic and abiotic factors will affect the bluegill in the lake? 3. 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…
- Science Name: Date: Class: Range of Tolerance Data Analysis One of the responsibilities of an aquatic biologist is to make sure that the abiotic factors stay wiumh the acceptable ranges for the optimal help for the Species within the local ecosystem. Bcologists, including aquatic biologists, use the range of tolerance to monitor the number of different populations residing in the area. m order to do so they use statistical models. Create a graph displaying on the x-axis the ranges of abiotic conditions such as temperature to study the population of rainbow trout in the area ( use the launch model as an example), Label each interval with temperature range and condition. What Causing Stress in Rainbow Trout Population The optimal range is the amount of an abiotic factor that produces the highest possible population. For water temperature, this would be about 6-10°C. Label this area on the graph. 1. 2. The zone of physiologic stress occurs when an abiotic factor exists at levels that are…Organisms at a higher trophic level have less energy available.comment.A class is studying the tropic levels of an ecosystem. The pyramid of biomass shown is a model of these trophic levels. Which of the following is the best explanation of the available energy at each of the trophic levels in this ecosystem ?

Explain how their size affects or is affected by the dynamics of energy, biomass and/or numbers pyramids. 7. What other factors in an ecosystem may affect pyramid shapes for that ecosystem? 8. What level of an ecological pyramid would contain humans? Please explain your choice. 9. Many farmers use pesticides on their fields to keep pests from eating their crops. These pesticides, however, can have serious, negative effects on other organisms thaat interact with the ecosystem. For that reason, some people have suggested that bringing in predators to eat the pests would be a better soulution than pesticides. a. Explain what affeccts bringing predators in could have on the ecosystem. b. Which level of organisms is most susceptible to extinction.
