16
Q

What are density-dependent factors

A

Any force that affects the size of a population of living things in response to the density of the population (tend to be abiotic)

17
Q

What are density-independent factors

A

Any force that affects the size of a population of living things regardless of the density of the population (tend to be abiotic)

18
Q

Examples of density-dependent factors

A

Competition for water, Disease

19
Q

Examples of density-independent factors

A

Flood, Drought

19

Meaning of N o

A

constant representing initial population size

20
