1. 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: ????

2. An organism’s role in its environment is its niche. If two species are trying to use the same niche, competition will occur and only one species will successfully survive there.

3. Symbiosis is a relationship where two organisms live very close to one another. There are three major types of symbiotic relationships. 1.Mutualism – both organisms benefit. Sea anemone and clownfish

4. 2. Commensalism – one organism benefits, the other is neither benefits nor it harmed. bird and capybara

5. 3. Parasitism – a symbiotic relationship where one organism benefits and the other organism is harmed. parasitic videos

6. AP Bio: Aposematic coloration Batesian mimicry Mullerian mimicry

7. Ecological Succession is a series of predictable changes in abiotic and biotic parts of a community of organisms over time. Succession starts with pioneer organisms and over many years results in a climax forest community that is very stable.

11. Primary succession would occur on rock after a volcanic eruption. Secondary succession would occur after a man-made disturbance such as a fire or deforestation.

14. Renewable Resources – can be restored during your lifetime. Non-renewable Resources – cannot be restored during your lifetime.

15. Burning non-renewable resources (fossil fuels) as an energy supply causes an increase in production of greenhouse gases like….. This may lead to global warming.

16. 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.

17. Burning non-renewable resources (fossil fuels) as an energy supply causes environmental problems like acid rain because…..

18. 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 harmful ultraviolet light.)
