Front

What is a uniform population distribution?

Back

A uniform population distribution is a pattern where individuals are evenly spaced across a given area, often seen in species like bears.

Front

What does a survivorship curve illustrate?

Back

A survivorship curve illustrates the number of individuals born during the same interval that remain alive over time.

Front

What is logistic growth in population dynamics?

Back

Logistic growth is a population growth pattern where a population grows slowly at first, followed by a period of exponential growth before stabilizing at a stable size, producing a characteristic S-shaped curve.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals that the population's environment can support indefinitely.

Front

What is an example of a density-dependent factor?

Back

Diseases are an example of a density-dependent factor, as their impact on a population increases with population density.

Front

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

Back

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

Front

What is exponential growth in population dynamics?

Back

Exponential growth is a pattern where a population increases rapidly without any limits, often seen in ideal conditions.

Front

What is the significance of the S-shaped curve in population growth?

Back

The S-shaped curve indicates that a population grows slowly at first, then rapidly, and finally stabilizes as it reaches its carrying capacity.

Front

What role do resources play in population dynamics?

Back

Resources such as food, water, and shelter are crucial for population growth and survival; their availability can limit or support population size.

Front

What is the impact of overpopulation on ecosystems?

Back

Overpopulation can lead to resource depletion, habitat destruction, and increased competition, ultimately harming the ecosystem.
