Every yeаr, Prоfessоr Angillettа (BIO320 cоurse creаtor) cleans up the leaves dropped by the Palo Verde trees in his backyard. As much as he hates this yard work, he loves burning the leaves in his fire pit. This year, his wife encouraged him to throw the leaves into the trash instead of burning them. The trash would be picked up and taken to a dump outside of town. At the dump, the leaves would be buried with other trash and left to decompose. Being an ecologist, Professor Angilletta wondered about the effect that each option would have on the environment. a) Describe the way that carbon and nitrogen from leaves would flow through an ecosystem if they were: (i) burned in a fire or (ii) buried in the ground. Specify forms of carbon and nitrogen that are generated by each option, and which biotic or abiotic component/s of the ecosystem that would use the compounds. b) Given your knowledge of ecology and the environmental issues that currently threaten biodiversity, recommend which option Professor Angilletta should choose to minimize negative effects on biodiversity. Explain your reasoning. RUBRIC: In a), describing the forms and flow of carbon and nitrogen is worth 3 points for burning, and 3 points for burying (6 points in total). In b), a detailed answer including a clear recommendation is worth up to 4 points. To facilitate accurate grading, label your answer to each part (a, b) and separate with a blank line. [Maximum 10 sentences (4 sentences in a, 6 sentences in b). Maximum 10 points]
