Front

How do ecologists study populations?

Back

Ecologists study populations by examining geographic range, density and distribution, growth rate, and age structure.

Front

What is a population?

Back

A population is a group of organisms of a single species that lives in a given area.

Front

What is density-dependent competition?

Back

Density-dependent competition occurs when individuals compete for resources, and the competition intensity increases as the population density increases.

Front

What happens when the birth rate equals the death rate in a population?

Back

The population is remaining constant in size.

Front

What type of growth is Mexico experiencing due to a higher number of children than adults?

Back

Mexico is experiencing a rapid growth rate.

Front

Define geographic range in population ecology.

Back

Geographic range refers to the area in which a population is found.

Front

What is population density?

Back

Population density is the number of individuals of a species per unit area.

Front

Explain age structure in a population.

Back

Age structure is the distribution of individuals of different ages within a population.

Front

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

Back

Density-dependent factors are influenced by population size, while density-independent factors affect populations regardless of their size.

Front

What is carrying capacity?

Back

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