Front

Density-Independent factors

Back

Factors that affect all populations similarly regardless of population size. Examples include natural disasters, rapid climate changes (drought or floods), and human activity.

Front

Type III survivorship

Back

A pattern of survival where there is low survivorship early in life, with few individuals reaching adulthood.

Front

Generalists

Back

Species that have a wide range of dietary options and a relatively large area of habitat.

Front

Density-Dependent factors

Back

Factors that affect a population depending on its size, including food availability, predation, parasitism, and disease.

Front

Type I survivorship

Back

A pattern of survival that tracks organisms with low death rates and high survivorship rates early in life, with a dramatic increase in death rate toward the end of their life expectancy.

Front

Carrying Capacity

Back

The maximum population size that an environment can sustain indefinitely without being degraded.

Front

Biotic factors

Back

Living components of an ecosystem that affect population dynamics, such as competition, predation, and symbiosis.

Front

Abiotic factors

Back

Non-living components of an ecosystem that influence population dynamics, such as temperature, water, and nutrients.

Front

K-selected species

Back

Species that produce fewer offspring but invest more resources in raising them, leading to higher survival rates.

Front

r-selected species

Back

Species that produce many offspring with little parental care, leading to lower survival rates.
