1.

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

a)

succession

b)

adaptation

c)

evolution

d)

progression

2.

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.

a)

primary

b)

secondary

c)

tertiary

d)

pioneer

3.

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.

a)

primary

b)

secondary

c)

tertiary

d)

pioneer

4.

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.

a)

pioneer

b)

self-perpetuating

c)

intermediate

d)

community

5.

This is an example of...

a)

primary succession

b)

secondary succession

c)

tertiary succession

d)

climax community

6.

The Ohia is the first species to inhabit new areas of lava flow. These plants are...

a)

pioneer

b)

self-perpetuating

c)

intermediate

d)

community

7.

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

a)

survivorship curve

b)

exponential

c)

linear

d)

logistic

8.

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.

a)

Type I

b)

Type II

c)

Type III

d)

Type IV

9.

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

a)

Type I

b)

Type II

c)

Type III

d)

Type IV

10.

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.

a)

k-strategist

b)

r-strategist

c)

m-strategist

d)

s-strategist

11.

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.

a)

k-strategist

b)

r-strategist

c)

m-strategist

d)

s-strategist

12.

This is an example of...

a)

primary succession

b)

secondary succession

c)

tertiary succession

d)

climax community

13.

parasitism and disease

d)

weather

14.

Click density independent factor(s).

a)

competition for resources

b)

predator-prey relationships

c)

parasitism and disease

d)

weather, natural disaster and man made disturbances

d)

18 hours - 24 hours
