Back

Living environmental factors that influence population size.

Front

Factors Increasing Population Size

Back

Immigration and natality are factors that increase population size.

Front

Population crash phase

Back

The crash phase is when the population size decreases rapidly after reaching a peak.

Front

Ecological balance

Back

Achieved when population size stabilizes around the carrying capacity.

Front

Carrying capacity is a key concept in population dynamics.

Back

It represents the limit of resources available to support a population.

Front

Resource availability is crucial for population sustainability.

Back

Without sufficient resources, populations cannot maintain their size.

Front

Examples of density dependent factors

Back

Territorial behavior, predation and competition, accumulation of waste, food, space and shelter, parasitism and disease.

Front

Density independent factors

Back

Factors that exert an influence on a population regardless of its size and are abnormal events in nature occurring randomly.
