survivorship curves, strategist & succession (ecology)

A series of predictable changes that occurs in a ecological community over time.

• succession

• adaptation

• evolution

• progression

The type of succession in which the initial conditions are very harsh & the conditions changes very slowly. Changes can take hundreds to thousands of year.

• primary

• secondary

• tertiary

• pioneer

The type of succession where the area has already been established but then disturbed or destroyed but the soil is still left intact and vegetation change happens much more quickly.

• primary

• secondary

• tertiary

• pioneer

Species that are able to in survive hostile environments. Usually autotrophs, these species are the first to colonize areas. Their niche is to create new ecological niches for other species.

• pioneer

• self-perpetuating

• intermediate

• community

NGSS.MS-LS2-4

A graph that shows the number or proportion of individuals surviving to each age for a given species or group.

• survivorship curve

• exponential

• linear

• logistic

Tracks organisms that tend to live long lives (low death rate and high survivorship rate); toward the end of their life expectancies, however, there is a dramatic increase in the death rate.

• Type I

• Type II

• Type III

• Type IV

Tags

NGSS.HS-LS4-5

Describes organisms with a high death rate (or low survivorship rate) immediately following birth. Examples include bacteria, fishes, and invertebrates.

• Type I

• Type II

• Type III

• Type IV

NGSS.HS-LS2-2

These organisms typically live in unstable, unpredictable environments & are able to reproduce rapidly (exponentially). They do not take care of their young & are subject to predation.
