Principles Of Biology Module 2 Notes

Ecosystem {Ans: Composed of all the biotic components (living things) in an area along with the abiotic components (non-living things) of that area}qualitative data {Ans: observation of appearance and presence}predation {Ans: [+,-]}competition {Ans: [-,-]}Second Law of Thermodynamics {Ans: In every energy transfer, some amount of energy is lost in a form that is unusable. In most cases, this form is heat energy.}primary succession {Ans: newly exposed or newly formed land is colonized by living things}logistic population {Ans: G = rN[(K-N)/K]}Type 1 survivorship {Ans: death primarily occurs in the older years}communalism {Ans: [+,0]}Trophic Level {Ans: composed of organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy}Sun {Ans: The main source of energy in almost all ecosystems}parasitism {Ans: [+,-]}Type 2 survivorship {Ans: death at any age is equally probable.}interspecific {Ans: Any interactions between two or more species}density-dependent {Ans: factors, in which the density of the population at a given time affects growth rate and mortality}autotrophs {Ans: auto=self, these organisms feed themselves, Photosynthetic autotrophs (photoautotrophs) use sunlight as an energy source, whereas chemosynthetic autotrophs (chemoautotrophs)
