Population 2

If the number of births in a population is the same as the number of deaths in a population, what will happen to the growth of the population?

• It will increase.
• It will decrease.
• It will stay the same.
• It will fluctuate.

what tells how fast a given population grows?

• exponential growth model

• population growth rate

• logistic growth model

• carrying capacity

A small island nation is tracking its total population.  It started with exactly 100 people. During the year, 10 people immigrated, while 20 emigrated.  The birth rate was 15, and the death rate was 5.  What is the new population of the country?

• 115

• 110

• 90

• No change; the population is still 100.

One of the Factors that affect population size:

INCREASE: Number of ___________

• Birth

• Death

• Emigration

• None of them

Does the graph represent an exponential growth or logistic growth?

• Exponential Growth

• Logistic Grwoth

What type of growth is shown on this graph?

• Logistic

• Exponential

• Carrying Capacity

A population will eventually reach carrying capacity because...

• There are infinite resources

• Limiting factors come will affect the population

• There are limited resources

• Both B & C

An example of a density dependent limiting factor is...

• an avalanche.

• the amount of available food.

• a sudden flood

• a decrease in water due to drought.

What term is described as: "The ability to produce offspring"?

• Mortality

• Fecundity

• Natality

• Seasonality

Which form of selection is commonly referred to as "Quick and Many"?

• r Selection

• K Selection
