Transcript of Biotic And Abiotic Factors

We are going to talk about the aspects of
biotic
and
abiotic
factors
Go in-depth of the relationships of the different biotic and abiotic factors:

Biotic & Abiotic Factors
Effect of Abiotic Factors on Biotic FactorsAir(Oxygen)
Most living organism breathes oxygen
Oxygen is a key factor for the survival of every biotic organism in the world
Without oxygen, most organism would not survive

Effects of Biotic Factors on Abiotic Factor
Effects of Biotic Factors on Abiotic Factors (Bacteria)
Soil organism maintain soil structures
Some bacteria in soil break down pollutants
Dead organisms increase soil quality
Animal waste can act as a fertilizer for soil (i.e. manure)


Plants use CO2 and release oxygen = improved air quality
Some plants release water vapor from their leaves (process called transpiration),influencing the amount of rainfall in area
Plenty of trees (i.e. rainforest)= can lower temperature and remove air pollutants
Plants consume water for growth and use their roots to hold soil in place

Biotic & Abiotic Factors
Biotic Factors:
Living
organisms in an environment (i.e. animals, insects, plants, bacteria)
Effect of Abiotic Factors on Biotic Factors (Light)
Plants absorb light for energy through photosynthesis
In marine ecosystems: deeper the water, the less light is received=fewer plants can grow
Light provides warmth for animals

Effect of Abiotic Factors on Biotic Factors (Soil)
Abiotic Factor:
Non-living components of an environment (i.e. rocks, sunlight, water, air)
Effect of Abiotic Factors on Biotic Factors (Water)
Soil affects terrestrial plants because plants take nutrients directly from the soil
Soil provides nutrients and shelter for many organisms (i.e. bacteria)
Soil acts as a habitat for many plants and living organisms
Without water, organisms would not be able to survive due to dehydration
Water is a necessity for living organisms to survive
Provides habitat for fish and other marine organisms
Water carries nutrients from one place to another
Plants depend on water for growth, nutrients and survival

Effects of Biotic Factors on Abiotic Factors (Animals)
Animals produce waste, then waste becomes nutrients in the soil
Earthworms break down soil and dig tunnels to allow water and nutrients to move easily through the soil
Ground beetles, store carbon by eating insects, because all living organism contain carbon
