Presentation Transcript

  1. Biotic & Abiotic Influences

  2. Biotic & Abiotic Influences Ecosystem: all the living organisms that share a region & their physical & chemical environment

  3. Biotic & Abiotic Influences Ecosystem: all the living organisms that share a region & their physical & chemical environment e.g. pond forest oasis

  4. Biotic & Abiotic Influences Biotic Factors: living things, their remains, and features, such as nests, associated with their activities

  5. Biotic & Abiotic Influences Biotic Factors: living things, their remains, and features, such as nests, associated with their activities Population: a group of individuals of the same species Community: all of the different species that interact in an ecosystem

  6. Biotic & Abiotic Influences Abiotic Factors: the non-living physical and chemical components of an ecosystem e.g. rocks oxygen water sunlight

  7. Biotic & Abiotic Influences Sustainable Ecosystem: an ecosystem that is maintained through natural processes

  8. Biotic & Abiotic Influences Sustainable Ecosystem: an ecosystem that is maintained through natural processes Sustainability: the ability to maintain natural ecological conditions without interruption or weakening

  9. Biotic & Abiotic Influences Limiting Factor: any factor that restricts the size of a population e.g. biotic: availability of food abiotic: access to water

  10. Biotic & Abiotic Influences Tolerance Range: the abiotic conditions within which a species can survive

  11. Biotic & Abiotic Influences Tolerance Range: the abiotic conditions within which a species can survive Key abiotic factors: -light availability -water availability -nutrient availability -temperature

  12. Biotic & Abiotic Influences Biotic Factors: interactions with other organisms influence a species' success e.g. Competition: two individuals vying for the same resource

  13. Biotic & Abiotic Influences Biotic Factors: interactions with other organisms influence a species' success e.g. Competition: two individuals vying for the same resource Predation: one individual feeds on another

  14. Biotic & Abiotic Influences Biotic Factors: interactions with other organisms influence a species' success e.g. Competition: two individuals vying for the same resource Predation: one individual feeds on another Mutualism: two individuals benefitting each other

  15. Biotic & Abiotic Influences Biotic Factors: interactions with other organisms influence a species' success e.g. Competition: two individuals vying for the same resource Predation: one individual feeds on another Mutualism: two individuals benefitting each other Parasitism: one individual lives on or in and feeds on a host organism

  16. Biotic & Abiotic Influences Biotic Factors: interactions with other organisms influence a species' success e.g. Competition: two individuals vying for the same resource Predation: one individual feeds on another Mutualism: two individuals benefitting each other Parasitism: one individual lives on or in and feeds on a host organism Commensalism: one individual benefits & the other neither benefits nor is harmed

  17. Biotic & Abiotic Influences Carrying Capacity: the maximum population size of a particular species that a given ecosystem can sustain -carrying capacity is set by the influences of all the biotic and abiotic factors over a long period of time -sustainable populations live at or below their carrying capacity

  18. Biotic & Abiotic Influences Carrying Capacity: the maximum population size of a particular species that a given ecosystem can sustain sustainable population

  19. Biotic & Abiotic Influences Carrying Capacity: the maximum population size of a particular species that a given ecosystem can sustain Is human population growth sustainable?
