What impact does environmental resistance have on a population? What kind of population
distribution patterns occur in communities? What will be an ideal response?
ANS:Answer
should include:
? Environmental resistance is the effect of limiting factors on an environment. Limiting
factors in an environment can slow the rate of population in addition to regulating the
distribution of organisms.
? A random distribution of a population indicates that there is no impact of one organism
on that of another. The conditions in the environment are the same throughout. This is a
very rare type of distribution.
? Clumped patches of distribution are the most common form of distribution. There are
optimal conditions that occur throughout the environment. Patches can be a result of
nutrient concentration, initial population dispersal, and social interactions.
? Uniform distribution occurs when the organisms in a community are equally spaced
from one another. This is the rarest form of distribution in communities.

The next large earthquake on the San Andreas Fault zone in California is considered likely to be ________
A) in northern California because the last major earthquake was in central California and the plate boundary is moving the stress to the northwest. B) in Southern California because it has been nearly 300 years since the last major earthquake in that area C) in San Francisco because large earthquakes there are thought to occur every 75 years and the last large earthquake was in 1906 D) All of the fault system is considered equally likely because the plate motion is uniform and all areas are affected equally.
