When a population reaches carrying capacity, growth slows due to limited resources and increased competition.

Age structure determines the proportion of individuals capable of reproduction, influencing population growth rate.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Interactions - Predation and Herbivory
Hurricanes and other natural disasters affect populations regardless of their density, making them density-independent factors.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Interactions - Predation and Herbivory
Earthquakes are density-independent because they impact populations regardless of their size.

Logistic growth slows as a population nears carrying capacity due to increased competition and limited resources.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Growth - Exponential and Logistic Models
Logistic growth is represented by an S-shaped curve, where population growth slows as it nears carrying capacity.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Growth - Exponential and Logistic Models
Exponential growth occurs when resources are abundant, allowing populations to grow without limits.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Growth - Exponential and Logistic Models
Age structure helps predict future population growth by showing the proportion of individuals in reproductive and pre-reproductive stages.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Growth - Exponential and Logistic Models
The logistic growth equation accounts for limited resources, with growth slowing as population nears carrying capacity (K).
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Growth - Exponential and Logistic Models
The equation dN/dt = rN represents exponential growth, where population increases rapidly without resource limitations.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Growth - Exponential and Logistic Models
Logistic growth considers carrying capacity, which limits population growth as resources become scarce.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Growth - Exponential and Logistic Models
Natality refers to the birth rate or the number of individuals born in a population per unit time.
