Biotic & Abiotic Influences

1. Biotic & Abiotic Influences LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

2. Biotic & Abiotic Influences Ecosystem: all the living organisms that share a region & their physical & chemical environment LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

3. Biotic & Abiotic Influences Ecosystem: all the living organisms that share a region & their physical & chemical environment e.g. pond forest oasis LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

4. Biotic & Abiotic Influences Biotic Factors: living things, their remains, and features, such as nests, associated with their activities LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

5. Biotic & Abiotic Influences Abiotic Factors: the non-living physical and chemical components of an ecosystem e.g. rocks oxygen water sunlight LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

6. Biotic & Abiotic Influences Sustainable Ecosystem: an ecosystem that is maintained through natural processes LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

7. 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 LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

8. Biotic & Abiotic Influences Limiting Factor: any factor that restricts the size of a population e.g. biotic: availability of food abiotic: access to water LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

9. Biotic & Abiotic Influences Tolerance Range: the abiotic conditions within which a species can survive LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

10. Biotic & Abiotic Influences Tolerance Range: the abiotic conditions within which a species can survive Key abiotic factors: -light availability -water availability -nutrient availability -temperature LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

11. Biotic & Abiotic Influences Biotic Factors: interactions with other organisms influence a species' success e.g. Competition: two individuals vying for the same resource LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

12. 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 LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

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 Mutualism: two individuals benefitting each other LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

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 Parasitism: one individual lives on or in and feeds on a host organism LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

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 Commensalism: one individual benefits & the other neither benefits nor is harmed LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

16. 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 LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

17. Biotic & Abiotic Influences Carrying Capacity: the maximum population size of a particular species that a given ecosystem can sustain sustainable population LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem

18. Biotic & Abiotic Influences Carrying Capacity: the maximum population size of a particular species that a given ecosystem can sustain Is human population growth sustainable? LG: to describe the limiting factors of ecosystems & how they affect the carrying capacity of an ecosystem
