Unit and Chapter pages- There are 10 total units, starting with Unit 0. Each consists of 2-3 chapters.
Each unit page should have sub-links to chapters (Ex: APES>Unit 0 >>Chapter 1)
Each chapter page should include
CHAPTER SUMMARY: This brief summary/reflection should be more than 5 sentences, less than 10, in your own words. Focus on what you took away from the chapter’s big ideas/concepts.
LINK TO TEXT: A link to the chapter pdf
CHAPTER FOLDER: A private link to your chapter subfolder (carefully set these permissions so that only you and Ms. Stewart have access to the folder and docs!). In this folder, you should have your:
chapter outline (Follow Chapter Outline Guidelines)
chapter vocabulary (optional, but helpful!)
chapter review questions (optional, but helpful!)
labs or activities from the chapter.
Useful Media: Videos, articles, etc.
Study Artifacts: Links to any study materials that you found helpful when preparing for the chapter test.
Chapter Summary
Chapter Summary
Energy and matter move from producers to primary, secondary, and tertiary consumers. While energy is ultimately lost as heat to the atmosphere, matter such as carbon, phosphorus, and nitrogen cycle through the ecosystem, as the producers and consumers are broken down by scavengers, detritivores, and decomposers. On average, only about 10% of the energy available in one trophic level is transferred to the next highest trophic level, which is referred to as ecological efficiency. Part of the reason for low efficiency is that a substantial portion of biomass in each trophic level is not digestible. Of the energy digested, a portion is used for day to day activities of the consumer, with a small portion remaining for the growth and reproduction of the consumer. This low efficiency also has implications for humans acting as primary versus secondary consumers. When food webs have a new species added or an existing species number reduced, the positive and negative feedback loops can have widespread effects on the other species in the food web because they are interconnected.
