B2h Sustainability

You need to be able to:

• Evaluate a conservation programme (why it is needed, why the species is at risk of extinction, what th programme does, is it successful?)
• Use whales as a case study species (why they are close to extinction, the value of living and dead whales, aspects of whale biology that are not fully understood, issues around whaling)
• Describe sustainable development using fish stocks and woodland as examples (what it is, importance of population size, waste products, food & energy, requirement of planning & cooperation, how it can protect endangered species)

B2g Population and Pollution

You need to be able to:

• Describe and discuss human population growth (exponential, consequences, who uses the most resources, who causes the most pollution)
• Explain the causes of global pollution issues (global warming including carbon footprints, ozone depletion and acid rain)
• Compare living and non-living methods of measuring pollution

1. Human population - where do you fit?
2. Bitesize notes on population and pollution
3. Defra and air pollution

B2f Natural Selection

You need to be able to:

• Describe the theory of evolution, and use it to explain evolution, extinction and the formation of new species over time
• Explain how beneficial adaptations occur and how they are passed on
• Use modern examples to show why Darwin's theory is now considered correct, and why Lamarck's was discredited

B2e Adaptations

You need to be able to:

• Explain how adaptations help organisms cope with environmental stresses (hot, cold, dry, predators, prey)
• Explain how better adapted organisms are better able to compete
• Describe organisms as generalists and specialists

B2d Interdependence

You need to be able to:

• Explain competition in living things (what they compete for, why they compete, inter/intra specific competition, ecological niches)
• Explain how interdependence leads to changes in population sizes
• Describe the parasitism and mutualism (using nitrogen fixing bacteria in root nodules as a mutualism example)

B2c Recycling

You need to be able to:

B2b Energy Flow

You need to be able to:

• Construct, use and explain different ways of displaying energy flows in nature (food chains, food webs, pyramids of number, pyramids of biomass)
• Use calculations to explain food chains (efficiency, limits on chain length, energy losses)
• Describe how excretory products and uneaten parts can form the start of new food chains

B2a Classification

You need to be able to:

• Explain natural and artificial classification (kingdoms, arthropods, genetic information, changes in classification systems, binomial naming)
• Explain some problems of classifying organisms (great variation within species, newly discovered organisms)
• Explain why some species are classified in one class, but have an appearance of another (e.g. Dolphins & whales)
