  1. VCE BiologyUnit 2Ecosystems

  2. Your Challenge(Final SAC – Yahoo!) • Create an interactive power point presentation or • Create an interactive poster (e.g lift the flap, pull outs, pop up etc.,) • Which illustrate/explain your understanding of ALL the following concepts on a single page which link to other pages/ illustrations/text • Use images / labelling/ text / hyper linking • These concepts will all appear on the exam so consider this a useful revision exercise and tool!

  3. The concepts Ecosystem Adaptations Trophic levels Cycles Relationships VERY useful general web links Communities

  4. Ecosystem • Ecosystem • Habitat • Ecological niche • Competition • Abiotic factors • Biotic factors • Bioaccumulation • Bioaccumulation and some examples

  5. Trophic levels • Heterotrophs • Autotrophs • Carnivore • Omnivore • Herbivore • Decomposers • Producer • First order consumer (Primary Consumer) • Second Order consumer (Secondary Consumer) • Third order consumer (Tertiary Consumer)

  6. Relationships • Symbiosis • Mutualism • Commensalism • Parasitism • Host • Predator / prey • Food chain • Food chain and energy transfer • Food Web • Energy transfer and loss • Energy transfer and loss

  7. Communities • Population • Population dynamics • Succession • Carrying capacity • Pyramid of biomass • Pyramid of numbers

  8. Cycles • Organic matter cycle • Nitrogen Cycle Carbon Cycle Nitrogen Cycle

  9. Carbon Cycle • How does this work? • Why is the concentration of CO2 in our atmosphere increasing?

  10. Adaptations • Explain how a reproductive strategy can increase the chance of survival of an organism and this in turn can impact on an ecosystem • Explain how a behavioural adaptation of one of your organisms increases its chance of survival in your ecosystem • Explain how a structural adaptation of one of your chosen organisms can increase the chance of survival of an organism and this in turn can impact on an ecosystem • Links – Plant adaptations/structures

  11. Nitrogen Cycle • What is it? • Why do plants need nitrogen? • Why is nitrogen important?

  12. Useful general web links • http://www.reec.nsw.edu.au/geo/scirrg/scrrg1.htm • http://www.roomd113.com/TAKS%20NOTES/Objective%203%20Ecosystem%20and%20Interaction.pdf • http://www.etap.org/demo/biology_files/lesson6/instruction6tutor.html
