The document discusses natural resources, carrying capacity, and population growth. It defines renewable resources as those that can be regenerated within a lifetime, and nonrenewable resources as those that take millions of years to create and cannot be regenerated within a lifetime. Examples are given of both. Carrying capacity is defined as the maximum population size an environment can sustain indefinitely, and factors that can change carrying capacity are described. Population growth is explained to initially grow slowly, then rapidly as carrying capacity is approached, before leveling off or crashing if the capacity is exceeded.

8. Progression of Population Growth in
Relation to Carrying Capacity
Exponential Population Growth:
1. Growth starts out slowly, enters a rapid growth phase and then levels off when the carrying capacity for that
species has been reached
2. The size of the population then fluctuates slightly above or below the carrying capacity.
3. Reproductive lag time may cause the population to overshoot the carrying capacity temporarily. Reproductive
lag time is the time required for the birth rate to decline and the death rate to increase in response to resource
limits.
4. In this scenario, the population will suffer a crash or dieback to a lower level near the carrying capacity unless a
large number of individuals can emigrate to an area with more favorable conditions.
An area's carrying capacity is not static. The carrying capacity may be lowered by resource destruction and degradation
during an overshoot period or extended through technological and social changes.
