Biotic & Abiotic Influences

Biotic & Abiotic Influences • Ecosystem: all the living organisms that share a region & their physical & chemical environment

Examples of Ecosystems Mountains in Colorado Coral Reef in Belize Arizona Desert

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.

Biotic & Abiotic Influences • Limiting Factor: any factor that restricts the size of a population: – Biotic: availability of food. – Abiotic: access to water.

Biotic & Abiotic Influences • Tolerance Range: the abiotic conditions within which a species can survive. – – – sunlight availability water availability nutrient availability Temperature p. H

Abiotic Influences • Abiotic Factors: the non-living physical and chemical components of an ecosystem. – Rocks – Oxygen – Water – Sunlight

Abiotic Factors • Climatic and Edaphic – Climatic: factors that relate to the weather. – Edaphic: factors that relate to the soil.

Climatic Factors • What climatic factors can be measured? – Light Intensity – Humidity – Wind speed – Temperature – Aspect – Slope

Edaphic Factors • What edaphic factors could we measure? – Soil p. H – Amount of water in soil – Soil Temperature – Soil Air – Soil Texture

Biotic 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.

Biotic Influences • Biotic Factors: interactions with other organisms influence a species' success. – Competition: two individuals vying for the same resource.

Biotic 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.

Biotic 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.

Biotic 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.

Biotic 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. – –

Biotic Factors Interact with each other in complex ways Also interact with abiotic factors in the ecosystem such as Dependent upon water, minerals, temperature, light Parasitism Mutualism Competition

Biotic 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.

The 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.

The 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.
