Bio Acc: Human Population, Succession & Biodiversity

Front

What is stable growth in human populations?

Back

Stable growth occurs when a population's size remains relatively constant over time, with birth rates approximately equal to death rates.

Front

What happens when a population exceeds its carrying capacity?

Back

The population starts to die off to return to carrying capacity.

Front

What is exponential growth?

Back

Exponential growth is a rapid increase in population size when resources are abundant, often represented by a J-shaped curve.

Front

What is logistic growth?

Back

Logistic growth is a model of population growth that levels off as the population reaches its carrying capacity, often represented by an S-shaped curve.

Front

What is carrying capacity?

Back

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

Front

What is an age structure diagram?

Back

An age structure diagram is a graphical representation of the distribution of various age groups in a population, which helps predict population growth trends.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of species, genetic diversity, and ecosystem diversity.

Front

What is succession in ecology?

Back

Succession is the process by which ecosystems change and develop over time, often following a disturbance.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but soil remains.

Front

What is the predator-prey relationship?

Back

The predator-prey relationship describes the dynamics between two species, where one species (the predator) hunts and consumes the other (the prey).
