APES Unit 3: Populations

Front

What type of survivorship curve does an r-selected species have?

Back

Type III survivorship curve, characterized by high offspring numbers with low survival rates early in life.

Front

What follows a population overshoot?

Back

A dieback, which is a rapid decrease in population size due to resource depletion.

Front

What does TFR stand for?

Back

Total Fertility Rate, which measures the average number of children a woman will have during her lifetime.

Front

What type of species is Scotch Broom?

Back

A generalist species, capable of thriving in various habitats and conditions.

Front

Which of the following is NOT a characteristic of a developing country?

Back

Low Total Fertility Rate (TFR) is not characteristic of developing countries.

Front

Define r-selected species.

Back

Species that produce many offspring with low parental investment, leading to high mortality rates in early life.

Front

Define K-selected species.

Back

Species that produce fewer offspring with high parental investment, leading to higher survival rates.

Front

What is the difference between a specialist and a generalist species?

Back

Specialist species thrive in a narrow range of environmental conditions, while generalist species can adapt to a wide variety of conditions.

Front

What is carrying capacity?

Back

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

Front

What is the demographic transition model?

Back

A model that describes the transition of a country from high birth and death rates to low birth and death rates as it develops.
