ATTESTED Q and A
Population correct answers Group of individuals that live in the same area at the same time
Population Ecology correct answers Study of how and why the number of individuals in a population
changes over time
Abiotic and biotic factors correct answers Determine the range of a species
Population density correct answers Number of individuals per unit area
Random population correct answers Position of each individual is independent of others
Clumped correct answers Organisms associate in groups
Uniform correct answers Even distribution associated with competition
Demography correct answers Study of factors that determine size and structure of populations through
time
Survivorship correct answers Proportion f offspring produced that survive to a particular age
Fecundity correct answers Number of female offspring produced by each female in the population
Life history correct answers How the organism allocates resources to growth, reproduction, and survival
Population Cycles correct answers Regular fluctuations in size that some populations exhibit
, Age pyramid correct answers Tends to be even in industrial populations of humans
Community correct answers Interacting species within a defined area
Commensalism correct answers (+/0) fitness goes up in one participant, no effect on other
Competition correct answers (-/-) individuals use the same resources, which are limited
Consumption correct answers (+/-) when one organism eats another
Mutualism correct answers (+/+) both organisms benefit
Niche correct answers Range of resources that a species is able to use/tolerate
Competitive Exclusion correct answers Not possible for species within the same niche to coexist
Niche differentiation correct answers When the weaker species of an overlapping niche retreats into an
area of non-overlap
Asymmetric competition correct answers One species suffers a greater fitness decline
Symmetric competition correct answers Both species have equal fitness decline
Fundamental niche correct answers Combination of conditions that the species will occupy in the
absence of competitors
Realized niche correct answers Portion of resources used when competition occurs
Change in resource use correct answers Niche differentiation
