Change in a population's gene pool over time ANS evolution
Science of the origins of biological diversity and its distribution ANS evolution
the most fundamental unit of ecology (membrane that separates internal processes from the external
environment ANS individual
individuals of the same species living in a particular area and interbreeding (geographic range,
abundance, density, change in size, composition) ANS population
populations of species living together in a particular area ANS community
one or more communities of living organisms interacting with their nonliving physical and chemical
environments (cycling of matter within and between ecosystems) ANS ecosystem
all ecosystems on earth (linked together by exchanges of wind and water and by the movement of
organisms) ANS biosphere
understands how adaptations or characteristics of an individual's morphology, physiology, and
behavior enable it to survive in an environment ANS individua approach
examines variation in the number, density, and composition of individuals over time and space. ANS
population approach
, understands the diversity and interactions of organisms living together in the same place ANS
community approach
describes the storage and transfer of energy and matter ANS ecosystem approach
examines movements of energy and chemicals over the Earth's surface ANS biosphere approach
a change in the frequency of alleles in a population through differential survival and reproduction of
individuals that possess certain phenotypes (individuals with higher fitness will pass more copies of
their genes to the next generation, and that phenotype will come to dominate ANS natural
selection
1. Individuals in a population vary in their traits
2. Some of these differences are heritable; they are passed on to offspring
3. variation in traits causes some individuals to experience higher fitness ANS Darwin's 4

when one organism consumes producers ANS herbivory
when two organisms that depend on the same resources have a negative effect on each other ANS
competition
· when two species benefit from each other ANS mutualism
