important considerations age, distribution, birth rate
when describing a population
habitat a community of organisms includes all of
the organisms that share
an example of a density- extreme weather
independent factor regulating
population growth
immigration dispersal of individuals into a population
ecosystem a community of interacting organisms and
their physical environment
photosynthesis the primary process by which energy
becomes available to organisms in an
ecosystem
abiotic compounds the nonliving components of an
ecosystem
, mutualism ecological concept illustrated in a food
web
limiting factor a factor that is required for the growth
and survival of an organism
equilibrium position the mean population level around which
a species' characteristics abundance
fluctuates in the species
many agricultural pests R strategists
species such as foliar
pathogens, aphids, mites, and
small seeded weeds are
considered
R strategists The population is still at low values
relative to the carrying capacity of the
environment and thus is growing
exponentially with intrinsic reproductive
rate r (when it is not subject to
environmental perturbations.)
biodiversity level is lower in an agro-ecosystem compared to a natural
system
the goal of pest eradication to eliminate newly invading pests
secondary pests become after control actions have been taken to
prevalent control key pests
