growth? J or S

“J”

Explain exponential growth.

Exponential growth refers to growth of a population at a constant rate; only under ideal conditions

yes…a population can have more deaths than

births

Population II: 400

List and describe two of the three three types of

geographic distribution

1.Random- no order2.Clumped- grouped3.Uniform- orderly; a

pattern; evenly dispersed

Page 12: Misc. Ecological Relationships Ecological Succession Population II Population I 500 400 300 200 100 200 300 400 500 100 200 300 400 500 100 200 300 400.

Population II: 500

Is disease density-dependent or independent?

Why?

Density-dependent; disease will only become limiting

when the population is large and dense

disturbance.

Succession: 500

What is a pioneer species?

A pioneer species is the first species to move into or populate an area. For

example: lichen or algaePioneer species are responsible for

beginning the process of soil creation.
