2.5 Population Ecology

Front

What is logistic growth?

Back

Growth that occurs when a population's growth rate decreases as it approaches the carrying capacity due to limited resources.

Front

What type of growth is characterized by a J-shaped curve?

Back

Exponential growth.

Front

What shape does the graph of logistic growth typically take?

Back

S-shaped.

Front

Under ideal conditions with unlimited resources, what type of growth will a population exhibit?

Back

Exponential growth.

Front

What is the carrying capacity?

Back

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

Front

What is a limiting factor?

Back

Any resource or condition that limits the growth, abundance, or distribution of an organism or population.

Front

What does intraspecific competition refer to?

Back

Competition among individuals of the same species for limited resources.

Front

What is the difference between exponential and logistic growth?

Back

Exponential growth occurs without resource limitations, while logistic growth accounts for carrying capacity and resource limitations.

Front

What happens to the population growth rate as it approaches carrying capacity?

Back

The population growth rate decreases.

Front

What is a survivorship curve?

Back

A graph that represents the number of individuals in a population that survive to different ages.
