U3L5 Population Dynamics

Front

What is carrying capacity?

Back

The maximum population size that an environment can sustain indefinitely without being degraded.

Front

What does exponential growth look like on a graph?

Back

A J-shaped curve where the population size increases rapidly over time.

Front

What is logistic growth?

Back

A pattern of growth where a population grows rapidly at first, then slows as it approaches carrying capacity.

Front

What factors can limit population growth?

Back

Limited resources, predation, disease, and competition.

Front

What is density-dependent growth?

Back

Population growth that is influenced by the population density, such as food availability and space.

Front

What is density-independent growth?

Back

Population growth that is not affected by population density, such as natural disasters.

Front

How does a population with limited resources typically grow?

Back

It shows logistic growth, where growth slows as resources become scarce.

Front

What is the difference between exponential and logistic growth?

Back

Exponential growth occurs without limits, while logistic growth accounts for resource limitations.

Front

What does a logistic growth graph look like?

Back

It starts with a rapid increase, then levels off as it approaches carrying capacity.

Front

What is the significance of Point E on a population growth graph?

Back

It represents the carrying capacity of the environment.
