- Why conserve Wildlife?
- Medical Benefits
- Physiological research
- Many species for research such as nerve function,leprosy & drug teratology (causes of birth defects
- Nerve function - Squid have wider nerve cells that are easier to study than mammal nerves. Improved understanding of heart disease, stroke
- Leprosy - Armadillo are among the few animals that can catch leprosy &are used in the study disease & production of vaccinations
- Many species for research such as nerve function,leprosy & drug teratology (causes of birth defects
- Development of new medicines
- Many plants produce biologically active chemicals - medical uses in treating human disease
- Poppies - painkillers morphine & codeine
- Yew tree - Taxol for breast cancer
- Cinchona tree from South America - Quinine for malaria protection
- Many plants produce biologically active chemicals - medical uses in treating human disease
- Physiological research
- Resources
- Wood for construction, paper, fuel, resins
- Insecticides
- Cosmetics
- Dyes
- Earths life support systems
- Role of plants in hydrological cycle
- Transpiration & Interception
- Soil formation
- Organisms release nutrients from dead organic matter.
- Foliage & roots of plants help protect soil by reducing erosion caused by wind & water
- Species Interdependence
- Food supplies
- Pollination - flowers pollinated by animals. More reliable than wind pollination
- Seed dispersal - Animal dispersal more reliable than wind dispersal.
- Habitat provision - one species may provide a habitat for others.e.g. birds nesting in trees
- Role of plants in hydrological cycle
- Medical Benefits
- Fibres - cotton, wool, flax, hemp
- Resources
- Wood for construction, paper, fuel, resins
- Insecticides
- Cosmetics
- Dyes
- Resources
- Maintenance of atmosphere

- Role of plants in hydrological cycle
- Organisms that photosynthesis remove CO2 and release oxygen
- Earths life support systems
- Look at conditions for life on Earth for why
