1
Interdependence BTEC
2
Scenario: You are working for a conservation group, and have been asked to prepare a leaflet for local industry describing how organisms are adapted to their habitat, and the sensitive interdependency of species within the habitat. You will need to hand in a leaflet for this assignment.
3
Food chains and food webs Give two or three examples of food chains Explain the words: producer, consumer, primary consumer, secondary consumer, herbivore, carnivore, omnivore Try BBC Bitesize – food chains Do not copy the food chain from the web site Read through the pages Do the test bite
4
parasite and host Explain what the words mean Give two or three examples Try http://wonderwise.unl.edu/12parasi/kidactivi ty/index2.htm http://wonderwise.unl.edu/12parasi/kidactivi ty/index2.htm For examples
5
predator and prey Explain what the words mean Give two – three examples Try http://idahoptv.org/dialogue4kids/season4/prey/facts. cfm http://idahoptv.org/dialogue4kids/season4/prey/facts. cfm Display a predator/prey graph and explain why it look like that try http://algebralab.com/practice/practice.aspx?file=Read ing_PredatorPrey.xml http://algebralab.com/practice/practice.aspx?file=Read ing_PredatorPrey.xml Do the answers to the questions under the graph
6
Darwin’s finches Find out and explain how Darwin used the different types of beak of species of finches to explain how evolution can change animals Try http://www.bbc.co.uk/schools/gcsebitesize/sc ience/edexcel_pre_2011/environment/evoluti onrev3.shtml http://www.bbc.co.uk/schools/gcsebitesize/sc ience/edexcel_pre_2011/environment/evoluti onrev3.shtml
7
Natural Selection Find out about the peppered moth Explain how the peppered moth is an example of natural selection in action Try http://science.discovery.c om/interactives/literacy/ darwin/darwin.html http://science.discovery.c om/interactives/literacy/ darwin/darwin.html Play the survival game http://www.bbc.co.uk/sch ools/gcsebitesize/science/ 21c/life_on_earth/theory_ evolutionrev7.shtml http://www.bbc.co.uk/sch ools/gcsebitesize/science/ 21c/life_on_earth/theory_ evolutionrev7.shtml
8
MRSA Find out about how each generation has lots of organisms that die before they reproduce. The ones that live have features that help them survive. MRSA is a bacteria that now has a special feature that helps it survive antibiotics Explain this in your own words http://www.bbc.co.uk/schools/gcsebitesize/science/21 c/life_on_earth/theory_evolutionrev7.shtml http://www.bbc.co.uk/schools/gcsebitesize/science/21 c/life_on_earth/theory_evolutionrev7.shtml Or http://en.wikipedia.org/wiki/Antibiotic_resistance But scroll down until you find the diagram and explanation on the right hand side
9
Task 1 – produce a leaflet (describe the interdependence and adaptation of organisms) Research a specific habitat, and describe how organisms within the habitat are adapted for survival there.
10
e.g. a pond
11
Draw a simple food web Choose 2 or 3 of the organisms and explain how they are adapted to live in the pond Try http://www.britishecologicalsociety.org/docu ments/education/adaptations_ponds.pdf http://www.britishecologicalsociety.org/docu ments/education/adaptations_ponds.pdf But use your own words and pictures
12
Then, using words and food chains, describe how the organisms present are interdependent. (P3) That means pick out some food chains from the food web and show they are predator/prey and need food to live Also how plants provide the oxygen Etc. ALL STILL IN THE LEAFLET – IN YOUR OWN WORDS
13
Task 2 (describe how variation within a species brings about evolutionary change) Still in your leaflet Using the different species of finch studied by Charles Darwin as an example, describe how variation within a species can lead to evolutionary change. (M1)
14
Task 3 (explain how organisms within an ecosystem interact over time) Choose a predator/prey relationship from your selected habitat and explain how the species population of each may change over time. (M2)
