**__Science 10 - Thursday, February 10__**

 * ===**What are the most important questions we need to focus on....?**===
 * [|(The Cambridge 100 Questions Project)]
 * ===**Big Questions for Science today:**===
 * ===How can //**energy flow**// through an ecosystem be modelled?===
 * ===What happens to the amount of //**available energy**// from one //**trophic level**// to the next?===


 * ===**Terms so far...**===
 * abiotic ||< commensalism || biodegradation ||
 * adaptation || competition || consumers ||
 * biome || ecosystem || decomposers ||
 * biotic || mutualism || food chain ||
 * climate || niche || food pyramid ||
 * climatograph || parasitism || food web ||
 * || predation || producers ||
 * ||  || trophic level ||
 * ===**Work from last class to be turned in...****﻿**===
 * Chapter 1 Quiz
 * What Do You Know About Energy Flow?
 * Go With the Flow


 * **__Energy flow in the coral reef__**


 * **The arctic ocean is teeming with life**


 * **Seasonal environmental conditions in the Antarctic**


 * ===**Text Images - Pages 56-66**===


 * ===**Find Out Activity 2-1B - //Comparing Available Energy//**===
 * Use BLM 1-18 Chart to organize your information
 * Energy present for producers in Temperate Deciduous Forest = 8000 kcal/m2
 * Energy present for producers in Coniferous Forest = 6000 kcal/m2
 * Only 10% of Energy Present from a lower trophic level is available for the next trophic level
 * Cut each strip using the scale of 10 mm (1 cm) = 400 kcal/m2
 * Create two food pyramids that will look similar to Figure 2.13
