Decomposition chamber Organic matter — A mix of leaves, grass, and easily decomposed food such as fruit do not include citrus fruit or peelings should make up the material in this chamber. Aquatic chamber Water — Tap water may be treated with chemicals and so should not be used in the aquatic chamber. For more information about the Pearson Baccalaureate series please visit www. Why do you think this will be the case? Past questions are referenced at the end of each chapter in the book. Andrew worked in South East Asia for 10 years as part of the Royal Society's Rainforest Research Programme, examining the effects of rainforest disturbance on insect communities.
What this really means is that the energy conversions are never 100% efficient. Not only will you learn important concepts in a meaningful way, but you will also reflect on your knowledge and values, be able to seek and evaluate a wide range of views, and demonstrate the capacity to reason critically. Insects — Insects such as fruit flies Drosophila can fly between terrestrial and decomposition chambers and help decompose the detritus in the decomposition chamber. Strictly, closed systems do not occur naturally on Earth, but all the global cycles of matter, for example,the water and nitrogen cycles, approximate to closed systems. Cut 5, 2-litre fizzy drinks bottles as shown on left of figure, and assemble as indicated. During the course, students will study eight different topics. A reader requests expansion of this book to include more material.
They are referenced in the margins throughout the textbook and tie in with the topics explored. Feedback links involve time lags. Since there is disagreement in the literature regarding the definition of dynamic equilibrium, this term should be avoided. It will help you to prepare thoroughly and methodically for your examinations. Variables Ideally in an experiment one variable is changed the independent variable and one is measured the dependent variable.

Discussion and conclusions What were the main findings of your study? Evaluation What were the main limitations of your study include at least five? The content of the chambers is up to you — the figure and information contains suggestions page 3. As energy is dispersed to the environment, there will always be a reduction in the amount of energy pased on to the next trophic level. The specification in this catalogue, including limitation price, format, extent, number of illustrations and month of publication, was as accurate as possible at the time the catalogue was compiled. Pearson Baccalaureate Environmental Systems and Societies, 2nd edition is acomprehensive textbook that covers all eight topics from the course, along with advice on Internal Assessment, the Extended Essay, and links to Theory of Knowledge. The worksheet contains information about possible abiotic and biotic components for each ecosystem Artwork by Freddie Crossley.
Food chains and webs Draw food chains you expect to see in each chamber. He has published many articles on his insect work and maintains an active interest in tropical ecology and conservation. Be careful to select the fish carefully, and limit the number of larger organisms in this chamber. Feel free to contribute to this book, or ask questions on the. The problem is that once you have gotten your nifty new product, the environmental systems and societies pearson gets a brief glance, maybe a once over, but it often tends to get discarded or lost with the original packaging.
Diagrams Draw a diagram that shows your column of chambers and annotate the contents of each. Think carefully about what proportion of each of these components you should use. Transformations lead to an interaction within a system in the formation of a new end product, or involve a change of state. For example, predictive models of climate change may give very different results. In practice, some models require approximation techniques to be used. Click on the cover images below.
In ecosystems, there are many different variables operating at the same time. He has published many articles on his insect work and maintains an active interest in tropical ecology and conservation. Use the guidelines on pages 319—322 of the textbook to help you, and pages 4—5 of this worksheet. This course is designed to combine the techniques and knowledge associated with group 4 the experimental sciences with those associated with group 3 individuals and societies. Using water as an example, run-off is a transfer process and evaporation is a transformation process.
He was Head of Geography at St. For more information about the Pearson Baccalaureate series please visit www. There are many more titles in the Pearson Education Baccalaureate series. Here are some links to other resources you may find useful in your studies. © Pearson Education Ltd 2010. The terrestrial chamber should be watered regularly.
Do you want to put them in the terrestrial or decomposition chamber? In contrast, an aquarium may be a relatively simple ecosystem but demonstrates many ecological concepts. The investigation is submitted as a written report. What scientific theory did they illustrate? Download , available at www. Garrett Nagle has taught at St Edward's School Oxford since 1986. Does each organism appear at the same trophic level in each food chain? Make sure you include all relevant units. They are designed to help you practise for your exam, and full answers are provided so you can check your work. © Pearson Education Ltd 2010.
Each member of the class will have different components in their ecosystems — this will make comparisons between different ecosystems possible. Both laws should be examined in relation to the energy transformations and maintenance of order in living systems. Organisms you put in this chamber may need this substrate as part of their life cycle, or as a refuge. Pearson Baccalaureate Environmental Systems and Societies, 2nd edition is acomprehensive textbook that covers all eight topics from the course, along with advice on Internal Assessment, the Extended Essay, and links to Theory of Knowledge. The most productive soil is loam soil page 125.
