Biotic & Abiotic Influences

Biotic & Abiotic Influences

Ecosystem: all the living organisms that share a region & their physical & chemical environment

Biotic & Abiotic Influences

Ecosystem: all the living organisms that share a region & their physical & chemical environment

e.g. pondforestoasis

Biotic & Abiotic Influences

Biotic Factors: living things, their remains, and features, such as nests, associated with their activities

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 speciesCommunity: all of the different species that interact in an ecosystem

Biotic & Abiotic Influences

Abiotic Factors: the non-living physical and chemical components of an ecosystem

e.g. rocksoxygenwatersunlight

Biotic & Abiotic Influences

Limiting Factor: any factor that restricts the size of a population

e.g. biotic: availability of foodabiotic: access to water

Biotic & Abiotic Influences

Tolerance Range: the abiotic conditions within which a species can survive

Biotic & Abiotic Influences

Tolerance Range: the abiotic conditions within which a species can survive

Key abiotic factors:-light availability-water availability-temperature

Biotic & Abiotic Influences

Biotic Factors: interactions with other organisms influence a species' success

e.g. Competition: two individuals vying for the same resource

Biotic & Abiotic Influences

Biotic Factors: interactions with other organisms influence a species' success

e.g. Competition: two individuals vying for the same resourcePredation: one individual feeds on another

Biotic & Abiotic Influences

Biotic Factors: interactions with other organisms influence a species' success

e.g. Competition: two individuals vying for the same resourcePredation: one individual feeds on anotherMutualism: two individuals benefitting each other

Biotic & Abiotic Influences

Biotic Factors: interactions with other organisms influence a species' success

e.g. Competition: two individuals vying for the same resourcePredation: one individual feeds on anotherMutualism: two individuals benefitting each otherParasitism: one individual lives on or in

and feeds on a host organism

Biotic & Abiotic Influences

Biotic Factors: interactions with other organisms influence a species' success

e.g. Competition: two individuals vying for the same resourcePredation: one individual feeds on anotherMutualism: two individuals benefitting each otherParasitism: one individual lives on or in

and feeds on a host organismCommensalism: one individual benefits & the other neither benefits nor is harmed

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
