5.6 Population Dynamics FLASHCARD Review

Front

What is a biotic factor in population dynamics?

Back

A biotic factor is a living component that affects the population of organisms, such as predation, competition, and disease.

Front

What is the formula to calculate percent change?

Back

Percent Change = ((New Value - Old Value) / Old Value) x 100

Front

What is an example of a density-independent factor?

Back

Natural disasters are density-independent factors that affect population size regardless of the population density.

Front

What happens to the death rate as a country becomes more developed?

Back

The death rate typically decreases as a country becomes more developed due to better healthcare and living conditions.

Front

What is carrying capacity in population dynamics?

Back

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

Front

What is logistic growth in population dynamics?

Back

Logistic growth is a model of population growth that shows how a population grows rapidly at first and then levels off as it reaches carrying capacity.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components (like plants and animals), while abiotic factors are non-living components (like temperature and water).

Front

How does predation affect population growth?

Back

Predation can limit population growth by reducing the number of individuals in a population.

Front

What is the significance of resource availability in population dynamics?

Back

Resource availability affects population growth; limited resources can lead to competition and decreased population size.

Front

What is an example of a biotic interaction?

Back

An example of a biotic interaction is competition between two species for the same food source.
