Concepts Interdependence in ecosystems – food chains and food webs. Energy flows through food webs and is lost to heat and metabolism as it passes through each trophic level. (10% rule) Matter is recycled in ecosystems. Carbon, Nitrogen, Phosphorus. Populations of organisms grow exponentially if there are no factors limiting their growth. Limiting factors such as PREDATION, FOOD AVAILABILITY, COMPETITION AND DISEASE limit the size of a population. (constraint)

Actions REPETITION! – watch small, important, segments of the videos over and over and over and over and over and over and over and over and over………………….. EXPLAIN OUT LOUD – explain a concept out loud to someone. DESCRIBE and EXPLAIN important graphs and diagrams to someone. VIDEO RECORD YOURSELF – Explain concepts on video and then WATCH IT! Only YOU can make yourself adopt these habits. Will you do it?
