QUESTIONS WITH ANSWERS GRADED A+
>> africna elephants decline caused by
Answer: poaching, habitat destruction, disease, loss of genentic diversity,
climate chnage
>> ecology
- the factors and interactions that determine distribution and abundance
- where are they, how many are there, and why
- ernst haeckel 1866
Answer: - the study of the distribution and abundance of organisms
>> abiotic environment
- temp, light, nutrients, water
Answer: non living chemicla and physical factors
>> biotic environment
- other orgs, comp, predation
Answer: living/biological factors
>> interaction
- orgs affected by environment but presence also chnages environemnt
Answer: - abiotic and biotic components interact
>> biosphere
- regions of the atmosphere, hydrosphere, and lithosphere occupied by living orgs
Answer: largest biological organization scalar quantity
,>> ecology biological scale
ecosystem
community
population
organism
Answer: biosphere
>> organism
Answer: single individual of a single species
>> population
Answer: inidividuals of same species living in same geographical area
>> community
Answer: 2 or more pops living in same geographical area
>> ecosystem
Answer: comprising the community and its interactions with its
physical/chemical environment
>> ecological evidence
2. manipulative field experiments
3. controlled lab experiments
4. math models
- for comparison: distribution and abundance of orgs in natural environment
Answer: 1. observation and monitoring natural environment
>> goal of ecology
Answer: observe patterns, describe processes, and use this info to predict,
manage, and control
>> methods of approach
, Answer: statistics and scientific rigor
>> statistics
Answer: estimates of pop parameters (numerical features of the population)
>> random sampling
- app of statistics attach level of confidence to conclusions thata re drawn from
the results of investigations
- allow to make conclusions at population level using sample data
Answer: ecology relies on obtaining estimates from representative samples
>> aristotle 350 BC
Answer: Historia Animalium, description of natural patterns and how
they're explained by natural processes
>> herodotus and plato
Answer: Providential Ecology idea of balance in nature
>> Graunt 1662, Leeuwenhoek 1687
- pop increases, food supply decreases, and so pop will decrease
Answer: Population Growth
>> Buffon 1756, Malthus 1798, Quetelet 1835, Verhulst 1838
Answer: population regulation
>> Farr 1843 (Farr's Rule)
Answer: density goes up, mortality also goes up bc disease and food
competition
>> Edward Forbes 1887, Henry Cowles 1899
- agrigations change in patterns in communtiies of plants
