VCE Biology Unit 2 Ecosystems
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 Trophic levels Relationships Communities Cycles Adaptations VERY useful general web links
4
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
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?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/structuresPlant adaptations/structures
11
Nitrogen Cycle What is it? Why do plants need nitrogen? Why is nitrogen important?
