Study Questions with 100% Correct
Answers | Latest Edition
1. Aristotle - ANSWER book: Historia Animalian
- natural patterns described by natural processes
2. Herodotus and Plato - ANSWER providential ecology
- balance of nature: everything in nature has its place and therefore
nothing goes extinct
3. Graunt and Leeuwenhoek - ANSWER population growth - microorganism
4. Population - ANSWER individuals of the same species living in the same
geographic area
- facts that affect population size composition
5. Organism - ANSWER a single individual of a single species
- behaviors, environmental physiology, motphology
6. Null Hypothesis - ANSWER data was collected due to random chance and
there is no association between variables
7. P-value - ANSWER probability level
p <0.05 reject null hypothesis
,8. Z-test - ANSWER how many standard deviations a datum is above or below
the mean
9. Z-test formula - ANSWER sample mean-population mean/(standard
deviation/square root of sample size)
10.Confidence Level - ANSWER 95%
11.Biogeographic regions - ANSWER boundaries set where species
composition changes drastically over short distances
12.Climate - ANSWER long-term average differences in the amount of solar
energy
Ex: temperature, precipitation, wind velocity
13.What creates the season - ANSWER the tilt of the earth at 23.5 degrees
14.Air circulation at equator - ANSWER hot, wet air rises creating low
pressure and cools at high altitudes causing rain
Biome - Tropical rainforest
15.30 degrees North and South - ANSWER Hot, dry air falls creating high
pressure
Biome - Desert
16.60 degrees North and South - ANSWER Cold, wet air picks up moister and
rises (low pressure)
Biome - Temperate rainforest
,17.Polar regions - ANSWER Cold, dry air descends (high pressure) on polar
regions
Biome - polar desserts
18.Biomes - ANSWER determined by climate
similar vegetation but not necessarily organisms
19.Buffon, Malthus, Quetelet, and Verhulst - ANSWER regulation of
population growth
20.Verhulst - ANSWER population growth equation (aka logistics equation)
21.Malthus - ANSWER essay: growth of population
- population growth geometrically and resources grow arithmatically
22.Farr - ANSWER increase density leads to increase in mortality
- 6th root
23.Forbs and Cowles - ANSWER regulation of community (succession)
24.Ross - ANSWER mathematical models
- malaria and how it spread
25.Tansley, Calmest and Elton - ANSWER founders of modern ecology
- from natural history to experimental
, 26.Carson - ANSWER Book: Silent Spring
- brought ecology to the general population
27.Abiotic - ANSWER nonliving chemical and physical factors
- temperature, light, water, etc.
28.Biotic - ANSWER living factors
- organisms, predation, competition
29.Interaction - ANSWER abiotic and biotic components interact
- organisms affect the environment and the environment affects the
organisms
30.Biosphere - ANSWER atmosphere, lithosphere, hydrosphere
- spatially large and temporally long
- know very little about
31.Ecosystem - ANSWER the communities together with the physical
environment
- abiotic and biotic factors in a given geographic area
- energy flow and cycling of nutrients among abiotic and biotic
organisms
32.Community - ANSWER 2 or more populations living in the same
geographic area
- interactions among organisms
33.Transplant experiment - ANSWER determine factors limiting distribution
move organisms from one environment to another and see if they survive and
reproduce
