Slide7Biotic & Abiotic Influences
Slide8Ecosystem:
all the living organisms that share a region & their physical & chemical environment

Examples of
Ecosystems
Slide10Biotic & Abiotic Influences
Sustainable Ecosystem:
an ecosystem that is maintained through natural processes.
Sustainability: the ability to maintain natural ecological conditions without interruption or weakening.
Slide11Biotic & Abiotic Influences
Limiting Factor:
any factor that restricts the size of a population:
Biotic: availability of food.Abiotic: access to water.
Slide12Biotic & Abiotic Influences
Tolerance Range:
the abiotic conditions within which a species can survive.sunlight availability
water availabilitynutrient availabilityTemperaturepH
Slide13Abiotic Influences
Abiotic Factors:
the non-living physical and chemical components of an ecosystem.Rocks
OxygenWaterSunlight
Slide14Abiotic FactorsClimatic and Edaphic
Climatic:
factors that relate to the weather.
Edaphic: factors that relate to the soil.

Slide17Biotic 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.
Slide18Biotic Influences
Biotic Factors:
interactions with other organisms influence a species'
success.Competition: two individuals vying for the same resource.
Slide19Biotic Influences
Biotic Factors:
interactions with other organisms influence a species'
success.Competition: two individuals vying for the same resource.Predation
: one individual feeds on another.
Slide20Biotic Influences
Biotic Factors:
interactions with other organisms influence a species'
success.Competition: two individuals vying for the same resource.Predation
: one individual feeds on another.Mutualism: two individuals benefitting each other.
Slide21Biotic
Influences
Biotic Factors:
interactions with other organisms influence a species' success.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.
Slide22Biotic Influences
Biotic Factors:
interactions with other organisms influence a species'
success.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.

Slide24Biotic 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.
Slide25Is
human population
growth sustainable?
Slide26Classify the factors in the picture as either biotic factors or abiotic
factors…
Slide27And in this one??
Slide28Decide: Biotic or Abiotic
Write A if Abiotic
_____ Mouse _____ Rocks
_____ Water _____ Fish _____ Paper _____ Glass _____ Aluminum _____ Wooden Ruler _____ Sand
_____ Clouds Write B if Biotic_____ Corpse _____ Snail _____ Vegetation_____ Bread Mold _____ Trees
_____ Soil_____ Plastic _____ Pipe _____ Air_____ Wind
Slide29The Deer Population
A field study was conducted to observe a deer population in a given region over time.
The deer were counted at different intervals over a period of 40 years. During this period of time both ranching and hunting increased in the study region.
A summary of the data is presented in the table.
Slide30The Deer Population
During which 10 year period did the greatest increase in the deer population occur?
State one possible action that could have been used to help maintain a more stable population of deer in the area.
Identify an abiotic limiting factor for the deer populations.Identify a biotic limiting factor for the deer populations.List two problems an overpopulation of deer can cause in the environment.
