QUESTIONS AND ANSWERS GRADED A+
2025/2026
Ecology - ANS -The study of the distribution and abundance of organisms
-the factors and interactions that determine distribution and abundance
Question Ecology answers... - ANS Where are they at, how many and why are they there?
Aristotle - ANS Historia animalium
Herodotus and Plato - ANS Providential Ecology
Graunt and Leeuwenhoek - ANS Population Growth
Buffon, Malthus, Quetelet, Verhulst - ANS Population regulation
Farr's Rule - ANS as the density of a population increases, the death rate will also increase
Edward Forbes, H.C. Cowles - ANS community regulation and succession
1 @COPYRIGHT 2026 ALLRIGHTS RESERVED.
, Robert Ross(1908) - ANS mathematical model of the spread of infectious disease
-systems analysis
some of the founders of modern ecology(exp): - ANS A.G. Tansley, F.E. Clements, Charles
Elton
Abiotic components - ANS non-living chemical and physical factors(temperature, light, water,
nutrients)
Biotic components - ANS living(biological) factors (other organisms, competition, predation)
Ecological Scales - ANS Biosphere>Ecosystem>Community>Pop.>Organism
Z test - ANS (sample mean-pop mean)/standard error-->(standard dev/sqrt sample size)
We reject the null hypothesis when... - ANS the p- value is less than the significance level of
.05
Biogeographic regions - ANS boundaries are set where species composition changes quickly
over short distances
Temperature - ANS tropics are hotter than temperate regions
-same amount of heat concentrated on smaller area at the tropics
-at poles solar radiation passes through a deep layer of atmosphere
