Unit 11 Review: Population Dynamics

Front

What is the S-Shaped (logistic) growth curve?

Back

A graph that shows population growth that is capped at a carrying capacity, indicating that growth slows as the population approaches this limit.

Front

Define Density-Independent factor.

Back

A factor whose strength does not depend on the number of organisms in the population, such as natural disasters like earthquakes.

Front

What is Density-Dependent factor?

Back

A factor whose effects on the population depend on the population density, such as competition for resources.

Front

What is carrying capacity?

Back

The maximum number of individuals of a species that an environment can support sustainably.

Front

What does a J-Shaped (exponential) growth curve represent?

Back

A graph that shows population growth without any limits, leading to rapid increases in population size.

Front

What is linear growth in population dynamics?

Back

A steady increase in population size at a constant rate over time.

Front

What is a limiting factor?

Back

Any resource or condition that restricts the growth, abundance, or distribution of a population.

Front

During which days is the birth rate higher than the death rate?

Back

Days 1-5.

Front

What kind of growth curve does logistic growth represent?

Back

A growth curve that starts exponentially but levels off as it approaches carrying capacity.

Front

Over which range of days is the birth rate equal to the death rate?

Back

Day 4 to Day 6.
