Topic 5: On the wild side (Edexcel A-level Biology A)

As the first topic to be taught at the start at the second year of the Pearson Edexcel A-level Biology A (Salters Nuffield) course, topic 5 is very important and the content includes the key reaction of photosynthesis. All 10 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:

• Understand 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 stages of succession from colonisation to climax community
• 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
• Be able to calculate net primary productivity
• Know the relationship between NPP, GPP and R
• The effect of temperature on the rate of enzyme activity
• Isolation reduces gene flow and leads to allopatric and sympatric speciation
