What is exponential growth in population dynamics?

Back

Exponential growth occurs when a population increases by a constant proportion over time, leading to a rapid increase in size when resources are abundant.

Front

What factors contribute to human population growth?

Back

Advances in medicine, sanitation, and farming practices contribute to human population growth, while advances in human evolution do not.

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population, often having a more significant effect in small populations.

Front

What is gene flow?

Back

Gene flow is the transfer of genetic material between populations, which can increase genetic diversity.

What does carrying capacity mean?

Back

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

Front

What is the difference between logistic and exponential growth?

Back

Logistic growth occurs when a population's growth rate decreases as it approaches carrying capacity, while exponential growth continues unchecked.

Front

What are density-dependent factors?

Back

Density-dependent factors are environmental factors whose effects on a population change as the population density changes, such as competition and predation.

Front

What are density-independent factors?

Back

Density-independent factors are environmental factors that affect populations regardless of their density, such as natural disasters.

Front

What is a population?

Back

A population is a group of individuals of the same species living in a specific area at the same time.

Front

What is a community in ecological terms?

Back

A community is a group of different species that live together in one area and interact with each other.
