Population growth Flashcard

Front

What is the current estimated global population?

Back

Approximately 8.0 billion people.

Front

What advantage do specialist species have in stable habitats?

Back

They thrive better in habitats that stay the same.

Front

What are the problems associated with densely populated areas?

Back

Disease spreads more quickly, competition for food and space may be higher.

Front

What is emigration in population dynamics?

Back

Emigration is when individuals move out of a population, leading to a decrease in population size.

Front

What type of survivorship curve do R-selected species typically exhibit?

Back

Type III survivorship curve.

Front

Define population density.

Back

Population density is the number of individuals living per unit area.

Front

What is the difference between immigration and emigration?

Back

Immigration is the movement of individuals into a population, while emigration is the movement out.

Front

What are limiting factors in population growth?

Back

Limiting factors are environmental conditions that restrict population growth, such as food availability, habitat space, and disease.

Front

What is exponential growth in populations?

Back

Exponential growth occurs when a population increases rapidly due to abundant resources.

Front

What is carrying capacity?

Back

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