Population Growth Dynamics:
Exponential Growth: Populations with abundant resources grow rapidly at an accelerating pace.
Logistic Growth: When resources become limited, populations follow a logistic growth curve, leveling off at the carrying capacity.
Phenotypic Variation and Competition: Individuals within populations vary phenotypically, leading to intraspecific competition for resources.
