Which of the following is density-independent limiting factor?
disease
competition
earthquake
predation
What causes competition to occur in an environment?
Good conditions make resources plentiful.
Organisms struggle for a limited resource.
Members of a population have different roles.
A population falls below the environment’s carrying capacity.
When individuals join a population
Aliens
migration

Emigration
To measure population density, you must divide the number of individuals living in a defined space by the
area of the space
birth and death rates
carrying capacity
height of the space
Diseases may spread more rapidly when an area is crowded, so disease is considered to be a
