Year 12 Ecology

Haven't found much!

• Ecology and grouping organisms - Ecosystems, classification or organisms, species definition. Two levels of quiz at the end.
• Primary succession on a glacial moraine - Nice description of how primary succession occurs after a glacial retreat.Watch the narrated animation.
• Coastal succession interactive - Interactive explains succession as the sea level falls.
• Mutualism interactive - Two examples of mutualistic relationships.
• Predator-prey cycles interactive - Have a play to see what happens to predator and prey population sizes when you fiddle with their reproductive rates and how many prey get eaten by each predator.
• Competition interactive - Gauses’ principle of competitive exclusion leads to zonation of barnacles on a rocky shore.
• Structure of the forest - A pdf document (so you need Adobe Acrobat reader) about the stratification in beech forest at Arthur’s pass. Text only. Boring!
• S-cool: Ecology - Ecology revision pages. Click through to the next topic. Covers: Who's Eating Who?; Populations; Adapting to Survive; Cycling Through Nature (including carbon and nitrogen). Has animations.
• Interpreting ecological data - Some graphs and tables etc. No answers.
• Predator prey interactions: graphing - Investigating and graphing patterns of deer populations, and changes with predator and prey. Don’t draw the graph; just look at the data and answer the questions.
• BBC Science: Biology: Populations and Pyramids - Food chains, pyramids, efficiency or production, competition, predator-prey cycles. Revision and a test at the end.
• BBC Science: Adapt to fit - Adaptations. Overly simple for this level.
