Biotic and Abiotic Factors
• Biotic Factors are the living components of an ecosystem. (predator/prey interactions)
• Abiotic Factors are the nonliving parts of the ecosystem. They are considered to be LIMITING FACTORS that determine which types of organisms can live there. Examples: ????
An organism’s role in its environmentis its niche.
If two species are trying to use the same niche, competition will occur and only one species will successfully survive there.
Symbiosis is a relationship where twoorganisms live very close to one another.
There are three major types of symbioticrelationships.
1. Mutualism – both organisms benefit.Sea anemone and clownfish
Renewable Resources – can be restoredduring your lifetime.
Non-renewable Resources – cannot be restored during your lifetime.
Burning non-renewable resources (fossilfuels) as an energy supply causes an increase in production of greenhousegases like…..
This may lead to global warming.
• Acid Precipitation – Precipitation with a pH level below 5.2.
• The primary cause is burning of fossil fuels which releases nitrogen and sulfur compounds that turn acidic when mixed with water vapor in the atmosphere.
Burning non-renewable resources (fossilfuels) as an energy supply causes environmental problems like acid rainbecause…..
Use of aerosol products and refrigerants causes the release of CFC’s (chloro-flourocarbons) into the atmosphere. This causes depletion of the ozone layer (which normally protects the earth from harmfulultraviolet light.)
