This concise lesson acts as an introduction to topic 5.3, Energy and Ecosystems, and describes how plant biomass is formed, measured and estimated. The engaging PowerPoint is the 1st in a series of 3 lessons which have been designed to cover the detailed content of topic 5.3 of the AQA A-level Biology specification.
A quiz round called REVERSE Biology Bingo runs throughout the lesson and challenges students to recognise the following key terms from descriptions called out by the bingo caller:
- community
- ecosystem
- abiotic factor
- photosynthesis
- respiratory substrate
- biomass
- calorimetry
The ultimate aim of this quiz format is to support the students to understand that any sugars produced by photosynthesis that are not used as respiratory substrates are used to form biological molecules that form the biomass of a plant and that this can be estimated using calorimetry. Due to the clear link to photosynthesis, a series of prior knowledge checks are used to challenge the students on their knowledge of this cellular reaction but as this is the first lesson in the topic, the final section of the lesson looks forwards and introduces the chemical energy store in the plant biomass as NPP and students will also meet GPP and R so they are partially prepared for the next lesson.

Bundle
Topic 5.3: Energy and ecosystems (AQA A-level biology)
All 3 lessons included in this bundle are detailed and engaging and have been planned at length to cover the content of topic 5.3 of the AQA A-level biology specification, which is titled energy and ecosystems. The lessons contain a variety of tasks which introduce the biological content and then provide the students with opportunities to assess their understanding. There are also prior knowledge checks to make links to content from earlier in topic 5 and in topics 1 - 4. All the answers to the checks are embedded in the PowerPoint. If you would like to check the quality of these lessons, download the lesson titled "GPP, NPP & N" as this has been shared for free.

Bundle
Topics 5.3 & 5.4 (AQA A-level biology)
All 6 lessons in this bundle are detailed, engaging and include regular understanding checks, with answers embedded into the PowerPoint, to allow students to assess their progress. They have been designed to cover all of the content included in topics 5.3 and 5.4 of the AQA A-level biology specification.

Bundle
Topic 5: Energy transfers in and between organisms (AQA A-level Biology)
Normally the first topic to be taught in the second year of the AQA A-level Biology course, topic 5 contains some very important biological processes which include photosynthesis, respiration and energy transfer between organisms. All 17 lessons included in this bundle are highly detailed and have been planned at length to ensure that students remain motivated and engaged whilst being constantly challenged on their current understanding. Links to previously-covered topics are also made throughout the lessons. The following specification points are covered in these lessons: TOPIC 5.1 * The light-dependent reaction of photosynthesis * The use of reduced NADP and ATP from the light-dependent reaction in the light-independent reaction * The light-independent reaction of photosynthesis * Environmental factors that limit the rate of photosynthesis TOPIC 5.2 * Respiration produces ATP * Glycolysis as the first stage of aerobic and anaerobic respiration * The conversion of pyruvate to lactate or ethanol in the anaerobic pathways * The link reaction and the Krebs cycle * Synthesis of ATP by oxidative phosphorylation * Other respiratory substrates TOPIC 5.3 * Gross primary production and net primary production * The net production of consumers * Farming practices designed to increase the efficiency of energy transfer TOPIC 5.4 * The role of microorganisms in the nitrogen cycle * The phosphorus cycle, including the role of saprobionts and mycorrrhizae * The use of artificial and natural fertilisers * The environmental issues arising from the use of fertilisers including leaching and eutrophication. If you would like to sample the quality of the lessons in this bundle, then download the chloroplast structure, anaerobic respiration, oxidative phosphorylation, GPP and phosphorus cycle lessons as these have been uploaded for free
