BioLab3 Ecology Concepts Lab Report Name, date, course and section required for password: The lab report is unique each semester and checks have been put into place to ensure students are doing their own work. Copying from other students or from outside sources will result in a zero on the accompanying lab quiz. Producers Distinguish between community and ecosystem. Name two examples. Describe the structure and ecology of Spirogyra. Why is it a producer? What are the spherical green structures in leaf cytoplasm? What is their function? Consumers Go to Lab, Section II, Exercise 2. Define and give an example of each of the following: primary consumer omnivore What is a Paramecium? Decomposers What is a decomposer? What is a detritivore? Give an example of a detritivore. What is the difference between hypha and a mycelium? What are rhizoids? Abiotic Material Name the molecules that cycle through living systems. What is abiotic material? Relationships Between Organisms What reactants combine in photosynthesis? What products are formed? What reactants combine in cellular respiration? What products are formed? Draw and label a food chain containing at least four trophic levels. Use specific organisms and identify each trophic level. Identify three abiotic components associated with the food chain. Sign, date and prepare an image of your drawing and include it with this lab report. What role does ATP play in metabolism? What is a trophic level? Based on Lab, Section V, Exercise 4, identify the organisms that compete for food in the food web. Competitors Flow of Energy How much of the producer’s energy is captured by secondary consumers? Draw and label an energy pyramid. Sign, date and prepare an image of your drawing and include it with this lab report. Summary Questions What is the difference between a food chain and a food web? What term is used to describe a secondary consumer? Explain how energy enters, flows, and exits an ecosystem. Explain how abiotic materials cycle in an ecosystem. Describe the difference between the movement of energy and the movement of abiotic materials in an ecosystem. What determines the trophic level to which an organism belongs? Name the four components of an ecosystem. Give an example of each. A program was introduced to improve fishing in a pond. First, fish were removed from the pond. Later, the pond was restocked with young carnivorous fish. Instead of growing into large fish, the new population contained many stunted individuals. Explain. © 2022 Access Learning Systems SP23
