Unformatted text preview: 3. Be able to differentiate between direct and indirect competition, interspecific
competition and intraspecific competition, and identify which is more common.
a. Indirect: quicker or more efficient use of a resource. More common
b. Direct: A fight or an attack over a resource.
c. Interspecific: Between species.
d. Intraspecies: Within a species. More Common.
4. Be able to identify the meanings or examples of the terms: Population, biotic
potential, environmental resistance, density-dependent factors, density
independent factors, carrying capacity.
a. Population: A Group of organisms that interbreed so as to produce viable
b. Biotic potential: The maximum intrinsic reproductive capacity of a population in
the absence of environmental interference.
dec. Environmental resistance: ecological features that inhibit population growth.
d. Density-dependent factors: Predators, Diseases, Food/water shortage, waste
buildup, lack of space.
e. Density-independent factors: Drought, Hotspells, Cold Snaps, Fires, and
f. Carrying Capacity: The environments ability to hold a specific number of
individuals for a prolonged period of time.
5. Be able to differentiate between S-shaped and J-shaped curves, identify which is
associated with exponential growth, which with logistic growth.
a. J is exponential and S shaped is logistic
6. Shown graphs of S- and J-shaped population growth, be able to identify the: lag
phase, acceleration phase, deceleration phase, equilibrium stage, carrying
capacity, maximum stationary phase, and crash phase.
