  1. Habitat: is the place or location where an organism lives. • Habitats are either: • terrestrial eg. • Aquatic • *freshwater eg. • *marine eg. • Estuarine eg. • Extreme Habitats: are locations that are hostile to live in. • Microhabitat: localized part of a general habitat where an organism lives. • Habitats provide resources such as: • f • w • s • b

  2. . • Community: refers to member of different species that share one habitat. • Migration: the movement of a species in a predictable way between widely separated habitats. This can be annual or once in a lifetime. Niche: refers to ‘way of life’ of a species or a species role in the community

  11. The factors that cause a particular condition in a habitat are called environmental factors and there are two categories 1.Abiotic

  12. 2.Biotic The environment in a habitat is produced by the action and interactions of several environmental factors

  13. In a rocky intertidal zone, what types of environmental factors may affect the distribution of these organisms?

  14. Measuring environments • Qualitative: • Quantitative:

  15. Micro-environment: refers to an environment found within an environment eg. Tolerance range: refers to the variation with which an organism can survive. It’s influenced by structural, physiological and behaviouralfeatures. Limiting factor: any environmental condition that restricts the types of organisms that can inhabit it.

  16. Limiting Factors

  17. Range: is the geographic area that encloses all the habitats where a species lives. NOTE: a large range doesn’t mean that a species is common and a small range doesn’t mean that a species is rare. Ranges alsodecrease and increase in size. Numbat: Why is the numbat range diminishing?

  18. Why is the cane toad population increasing?

  19. Tamar Wallaby Why would the heartleaf poison also be found in the range of the wallaby? What could gaps in the range mean? Why isn’t the range larger?

  20. Kultarr Large range but few sightings

  21. Technology to map range • Radio tracking: • Satellite tracking:

  22. Discuss with your partner various factors that may limit the “range” of an animal

  23. Seed Germination Practical • Germination: • process by which plants, fungus and bacteria emerge from seeds and spores, and begin growth. • Seeds remain dormant or inactive until conditions are right for germination. • Reproductive Strategies: • Contrasting reproductive strategies that are used by different species of animals to maximise survival • Eg. Rabbit vs Elephant

  24. Surviving Australian Desert Group Task

  25. Review Questions Chapter 9 • What is the difference between tolerance range and limiting factor? Give an example to illustrate your answer. • Terms or concepts not familiar with in glossary

  26. Recap of Chapter 9 • Niche + niche overlap • Make a concept map using 10 words of the glossary of Chapter 9

  27. Niche Overlap
