AP Biology Ecology

, Population - CORRECT ANSWERS-a localized group of individuals of the same
species that can interbreed, producing fertile offspring

Community - CORRECT ANSWERS-all the organisms that inhabit a particular area; as
assemblage of populations of different species living close enough together for potential
interaction

Ecosystem - CORRECT ANSWERS-all the organisms in a given area as well as the
abiotic factors with which they interact

Biotic - CORRECT ANSWERS-pertaining to the living organisms in the environment

Abiotic - CORRECT ANSWERS-nonliving; referring to physical and chemical properties
of an environment

Biosphere - CORRECT ANSWERS-the entire portion of earth inhabited by life; the sum
of all the planet's ecosystems

Niche - CORRECT ANSWERS-the sum of a species' use of the biotic and abiotic
resources in its environment

Clumped Distribution - CORRECT ANSWERS-individual aggregated patches, some
organisms group together where food is abundant

Uniform Distribution - CORRECT ANSWERS-evenly spaced, some organisms maintain
evenly distributed spacing to avoid aggressive interactions between neighbors

Random Distribution - CORRECT ANSWERS-unpredictable spacing, some plants grow
in random groups if their seeds were windblown across an area

Population Ecology - CORRECT ANSWERS-the study of populations in relation to their
environment, including environmental influences on populations, on population density
and distribution, age structure, and variations in population size

Sex Ratio - CORRECT ANSWERS-ratio of females to males within a population

Age Structure - CORRECT ANSWERS-the relative number of individuals of each age in
a population

Immigration Rate - CORRECT ANSWERS-the rate of influx of new individuals INTO a
population from other areas

Emigration Rate - CORRECT ANSWERS-the rate of movement of individuals OUT of a
population
