1. Homework Page 376 Understanding Key Concepts #5-#10 Lesson 35 Honors Biology

2. Character Education We learn about 10% of what is taught for most courses, this is not a rule as in ecology, learning is dependent on ability and most importantly, effort Lesson 35 Honors Biology

3. Objectives Describe the 10% rule Define biogeochemical cycle List examples of biogeochemical cycles Describe the parts of the water cycle Lesson 35 Honors Biology

4. Class Notes The amount of energy available to the next higher trophic level is about 10% of the lower level The number of trophic levels is not greater than 5, the number of levels is limited by the energy passed to the next level up The biotic parts of the environment are the living organisms and the a-biotic parts are the non living parts of the environment(heat,water,etc) Lesson 35 Honors Biology

5. Notes continued The water cycle includes: evaporation, transpiration, precipitation, and persperation The carbon cycle is effected by man’s activities including: burning fossil fuels, cutting down forests, and destroying photsynthetic organisms The nitrogen cycle is important because nitrogen is needed by animals in their proteins Lesson 35 Honors Biology
