Ecosystem Interactions Flashcards
What are the levels of Organisation
What is: Biosphere
Biomes
Ecosystem
Community
Species
Population
Give small definition
Biosphere: All areas if earth that support life
Biomes: Major terrestrial community found in diffrent area with similar climate
Ecosystem: All population in one area interacting including the enviroment (Like rain, co2,soil..)
Community: Interacting populations in one area
Species-A group of organisms that can interbreed
Population-A group of individuals of some species, interacting in one area
Organism-An living indivual
What is Abiotic Factors
The non living facotrs; tempretautre, precipitation,pH levels, salinity
What is Biotic factors
Living organisms, that shapes enviroment; producers, decomposers, prey species, competiers…
What is range of tolerence?
All species have requiremnts for the abiotic and biotic factors for them to survive.
What is a microhabitat?
It lies within the habitat, its the diffrence in physical condition;The top branches of a fern is dry, unlike below the fern.
What is a niche?
It is a role the organism plays in a community, how it interacts with others and uses resources
**No two organisms can occupy exactly the same niche at the same time, t
What are niche generalists and specialists?
Generalists:
Broader tolerances
Eats lots of types of food
Lives in many types of enviroments
Specialists:
Narriower Tolerances(More at risk)
Eats narrow range of food
Live in specific habitats
What is interdependent?
Organisms depend on each other for survival.(Interactions)
What is the interaction between different species called?
Interspecific interactions
What is the interaction between same species known as?
INTRASPECIFIC interactions
What is competetion?
When two species uses the same resources, theyre are competeting.It does not necassairality mean contact, it could be by means of effects on the resources- Indirect competetion
Define the types
Types of competition
Intraspecific- Competition between same species individuals
Interspecific-Competition between individuals of diffrent species
What is symbiosis
Is any close relationship living togerther of two specicies
What is mutalism(Expand on both types)
It is a win, win both benifit
Facultative mutualism:When both benifit but tbh like bros can survivie without each other
Obligate mutualism: Both needs each other to survive, bro pls I need u
What is commenalism?
It is when one species is benifited and the other is neither harmed or benifited. But it is found the other is sometimes benifited somehow.
Eg. Epiphyte grows on the surface of a plant for physical support and derives its moisture and nutrients from the air, rain, water or from debris accumulating around it. Not parasitic.
What is paratism?
Where an organism feeds/lives on host, host is often weaknd but not killed.
What is Amensalism
This is when one species incidently kills another species with no effect on the one doing the act. For example: Cattle trampling over vegetation
What is predation?
Organism feeds on another organism(Carnivores)
Review- Biosphere concept map
What is a producer?
(Autotrops) they make their own food, via photosynthesis or chemosynthesis
What is a consumer?
(Hetrotroph) Relys on other organisms for food by eating them.
What is a detrivore and decomposer?
Detrivore feeds on dead animals and waste products( Like earthworm and beetle)
Decomposer release chemicals to breakdown dead matter, they are the final breakdown of materials in a ecosystem(Fungi, bacteria)
Where does energy start from most of the time in a food chain?
Starts from the sun(or earths core)
What is a food chain?
Food chain is a series of steps in which organisms transfer energy by eating and being eaten
