What is exponential growth?

Back

Exponential growth is a type of growth where the population size increases at a constant rate, leading to a rapid increase over time.

Front

What is logistic growth?

Back

Logistic growth is a type of growth that starts exponentially but slows as the population approaches the carrying capacity of the environment.

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

What are limiting factors?

Back

Limiting factors are resources or conditions that limit the growth, abundance, or distribution of a population.

How does resource availability affect population growth?

Back

Resource availability directly impacts population growth; limited resources can slow growth and lead to a population decline.

What is the difference between density-dependent and density-independent factors?

Back

Density-dependent factors are influenced by population density (e.g., food, disease), while density-independent factors affect populations regardless of density (e.g., natural disasters).

Front

What is the formula for calculating population growth?

Back

The formula for calculating population growth is: Growth Rate = (Births - Deaths) / Total Population.

What is the significance of the growth rate in population studies?

Back

The growth rate indicates how quickly a population is increasing or decreasing, which is crucial for understanding population dynamics.

What happens when a population exceeds its carrying capacity?

Back

When a population exceeds its carrying capacity, it can lead to resource depletion, increased competition, and a decline in population size.
