NGSS.HS-LS4-5

An age-specific summary of the survival pattern of a population, it is best made by following the fate of a COHORT.

• life table

• death table

• birth table

• migration table

A graphic way of representing the data in a life table.

• survivorship curve

• exponential growth curve

• logistic growth curve

• lag phase

How many types of survivorship curves are there?

• 1

• 2

• 3

• 4

Survivorship curve represented with low death rates during early and middle life, then an increase among older age groups, a good example are humans.

• type I

• type II

• type III

• type IV

Survivorship curve represented by high death rates for the young, then a slower death rate for survivors, good examples are fish and frogs.

• type I

• type II

• type III

• type IV

Number of individuals per unit area or volume.

• denisty

• dispersion

• survivorship

• immigration
