QuestionAnswer
Population Growth Models Mathematical equations that can be used to predict population size at any moment in time
Population Growth Rate The number of offspring an individual can produce in a given time period, minus the deaths of the individual or its offspring during the same period
Intrinsic Growth Rate The maximum potential for growth of a population under ideal conditions with unlimited resources
Exponential growth model Growth Model that estimates a population's future size after a period of time, based on the intrinsic growth rate and the number of reproducing individuals currently in the population
J-Shaped Curve The curve of the exponential growth model when graphed
Logistic Growth Model A growth model that describes a population whose growth is initially exponential, but slows as the population approaches the carrying capacity of the environment
S-Shaped Curve The shape of the logistic growth model when graphed
Overshoot When a population becomes larger than the environment's carrying capacity
Die-Off A rapid decline in a population due to death
K-Selected Species A species with a low intrinsic growth rate that causes the population to increase slowly until it reaches carrying capacity
r-Selected Species A species that has a high intrinsic growth rate, which often leads to population overshoots and die-offs.
Survivorship Curves A graph that represents the distinct patters of species survival as a function of age
Type 1 Pattern of survival over time in which there is high survival throughout most of its life span, but then individuals start to die in large numbers as they approach old age
Type 2 Pattern of survival over in which there is a relatively constant decline in survivorship throughout most of the life span
Type 3 Pattern of survival over time in which there is low survivorship early in life with few individuals reaching adulthood
Corridor Strips of natural habitat that connects populations
Metapopulation A group of spatially distinct populations that are connected by occasional movements of individuals between them
Inbreeding depression you know what this means

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
