Succession (Edexcel Int. A-level biology)

Topic 5: Energy Flow, Ecosystems and the Environment (Edexcel International A-level Biology)

As the first topic to be taught at the start at the second year of the Edexcel International A-level Biology course, topic 5 is very important and the content includes the key reaction of photosynthesis. All 11 lessons included in this bundle are highly detailed and have been filled with a wide variety of tasks which will engage and motivate the students whilst covering the following specification points: * The overall reaction of photosynthesis * The phosphorylation of ADP and the hydrolysis of ATP * The light-dependent reactions of photosynthesis * The light-independent reactions of photosynthesis * The products of the Calvin cycle * The structure of the chloroplasts and the role of this organelle in photosynthesis * The absorption spectrum and action spectrum * Separating chloroplast pigments using chromatography and identifying them using retention factor values * Be able to calculate net primary productivity * Know the relationship between NPP, GPP and R * Understand the meaning of the terms ecosystem, community, population and habitat * The numbers and distribution of organisms in a habitat are controlled by biotic and abiotic factors * The concept of niche * The effect of temperature on the rate of enzyme activity and the calculation of the Q10 * Isolation reduces gene flow and leads to allopatric and sympatric speciation If you would like to sample the quality of the lessons in this bundle, then download the products of photosynthesis and succession lessons as these have been uploaded for free
