1.1 Ecosystems Flashcards
Ecology
Study of relationships between organism and their enviorments
Ecosystem
Particular location on Earth with interacting biotic and abiotic componets
Biotic
Living componets
Abiotic
Non-living componets
System
An assemblase of parts and the relationships between them which enable relatioships between them which enable them to work together to form a functioning whole
Open System
Exchange both matter and energy in system
Closed System
Only exchanges energy in system
Isolated System
Doesn’t exchange energy or matter
Species
Group of organism that can interbreed and produce fertile (can produce life) orgainsm
Hybrid
Offspring can live ot be adult but cannot reprodue
Niche
What makes organism unquie
population
Group of organisms of the same species living in the same area and can interbreed
Community
Group of populataions living and interacting together in a common habitat
Ecosystem
Coummunity of interdepentdent orgainism their physical environment
Interspecific Competition
Competition between different species
Intraspecific Competition
Competition between the same species
Why does competition occur
- Survial mode
- limited resources
- Nature is regulating population size
Simlar wants and need within species
Competitive Exclusion principle
Two species competing for the same resoures cannor coexsit
Resoruce pationing
usinf resources in different ways, places, or times
Autotroph
Make their own food through photosynthesis
Hetrotroph
Cannot make thir own food so they consume other organisms
Herbivore
only eats plants
Carnivore
Only eats meat
Omnivores
Eats plants and animals
Chemoautotrophs
Gains energy through chemical reactions (self feeder
Scavengers
Consumer dead animals, recycle organic matter and energy
Detritivores
Break down dead tissue waste porducts
Decomposers
Futurer break doen dead material, complete the process
Mutalism
both organisms benefit from their interactions (Clownfish + Coral reef )
Commensalism
One organism benefit while the other is netural about it
Parasitism
One orgainsm benfits while the other is harmed in the process
Amensalism
One organism is harmed while the other one is netural about it
Symbiosis
close and lng term interaction between 2 species in an ecosystem
