'GCSE (9-1) Food Chains Biology (Higher/Foundation) This video covers the animal food chain in-depth and with examples. An introduction and tutorial to the topic for beginners, explains in a basic and simple way to learn and easy to understand. Designed to help with school learning and completing homework and exam practice. This covers AQA GCSE (9-1) Specification Unit: 4.7.2.1 Levels of organisation. Students should understand that photosynthetic organisms are the producers of biomass for life on Earth. Feeding relationships within a community can be represented by food chains. All food chains begin with a producer which synthesises molecules. This is usually a green plant or alga which makes glucose by photosynthesis. A range of experimental methods using transects and quadrats are used by ecologists to determine the distribution and abundance of species in an ecosystem. In relation to abundance of organisms students should be able to: • understand the terms mean, mode and median • calculate arithmetic means • plot and draw appropriate graphs selecting appropriate scales for the axes. Applies to all UK exam boards: Pearson Edexcel, OCR-A, OCR-B,AQA and international GCSE (IGCSE) This video tutorial is designed to replicate and improve on other successful youtube channels such as Khan Academy, Freesciencelessons, Snaprevise, Examsolutions, The Organic Chemistry Tutor, Corbettmaths, Mathsgenie and others. We hope you enjoyed our explanations and it has helped you to better understand Maths and Science.
