Processes that remove individuals from a population.

• death and emigration

• birth and immigration

Individuals gather in patches, influenced by resource availability and behavior.

• clumped dispersion

• random dispersion

• uniform dispersion

• isolated dispersion

Individuals are evenly distributed, influenced by interactions between organisms in the population.

• uniform dispersion

• random dispersion

• clumped dispersion

• isolated dispersion

Position of each individual is independent of other individuals, occurs in the absence of strong attractions or repulsion's.

• random dispersion

• clumped dispersion

• uniform dispersion

• isolated dispersion

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

NGSS.MS-LS2-4

Survivorship curve represented by a death rate that is constant over organism’s life span, squirrels and songbirds are good examples.

• 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
