Population Growth and Survivorship Curves

Front

What is Type I survivorship curve?

Back

A survivorship curve where most individuals live to old age, typically seen in species that invest heavily in parental care.

Front

What is Type II survivorship curve?

Back

A survivorship curve where individuals have a constant chance of survival throughout their lives, often seen in birds.

Front

What is Type III survivorship curve?

Back

A survivorship curve where most individuals die young, with few surviving to adulthood, typical of species that produce many offspring.

Front

What is exponential growth?

Back

A growth pattern where the population size increases rapidly in proportion to the current population, often seen in ideal conditions.

Front

What is logistic growth?

Back

A growth pattern where the population grows rapidly initially but slows as it approaches carrying capacity, forming an S-shaped curve.

Front

What are abiotic factors?

Back

Non-living chemical and physical parts of the environment that affect living organisms, such as moisture, light, and minerals.

Front

What are biotic factors?

Back

Living components of an ecosystem that affect organisms, including plants, animals, and microorganisms.

Front

What is carrying capacity?

Back

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

Front

What is a predator-prey relationship?

Back

An ecological interaction where one organism (the predator) hunts and consumes another organism (the prey).

Front

What does a survivorship curve illustrate?

Back

It shows the number of individuals surviving at each age for a given species, reflecting their mortality rates.
