Population Ecology

Emigration is

• the movement out of an area

• the movement into an area

• movement in and out of an area

• migration

Why don't populations grow indefinitely?

• limiting factors

• only biotic factors

• only abiotic factors

• none of the above

What is an example of a density-independent (Abiotic) limiting factor?

• food

• parasites

• disease

• pollution

What is the arrow pointing at?

• carrying capacity

• biotic potential

• density-independent

• density dependent

parasites, disease, predators, are examples of what type of limiting factors?

• density dependent

• density independent

• survivorship

• type 1 curve

What is the carrying capacity mean?

• The number of individuals an area can carry

• the number of births

• The number of deaths an area has

• not sure

(Im)migration is ...

• the movement into an area

• The movement out of an area

• The migration process

• exponential graph

The exponential graph is a graph that shows us population size increasing quickly, which one below shows us that

• 

One of the factors that can change the size of population is....

• Name of schools

• Number of dezs

• Jobs

• Numbers of births

the number of people in a defined area such as a square kilometre

• population density

• birth rate

• death rate

• population
