What is population ecology?

Back

Population ecology is the study of how populations of organisms interact with their environment and how factors such as resource availability, competition, and predation affect population dynamics.

What is carrying capacity?

Back

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

What is emigration?

Back

Emigration is the movement of individuals out of a population, which can lead to a decrease in population size.

What is the difference between density-dependent and density-independent factors?

Back

Density-dependent factors, like competition and disease, have effects that vary with population density, while density-independent factors, like natural disasters, affect populations regardless of their density.

What is exponential growth?

Back

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

Front

What is a population?

Back

A population is a group of individuals of the same species that live in a specific area and interact with one another.

What role do natural disasters play in population ecology?

Back

Natural disasters are density-independent limiting factors that can drastically reduce population sizes regardless of the population's density.
