Total questions: 15
Worksheet time: 8mins
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
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
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
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.
k-strategist
r-strategist
m-strategist
s-strategist
These organisms occupy stable environments, are larger in size and have longer life expectancies. They produce, during their life spans, fewer offspring, but place a greater investment in each.
