Population Growth and Rate of Change

 

If the amount of food or resources available increases, the carrying capacity for an animal:

•  

  Fluctuates

•  

  Stays the same

•  

  Increases

•  

  Decreases

What type of growth is represented behind?

• Positive

• logistic

• exponential

• S-Curve

The two species, Paramecium aurelia and Paramecium caudatum, which do not prey upon each other, fighting to grow in the same test tube is an example of which of the following?

• Emigration

• Predation

• Competition

• Immigration

What does a limiting factor do?

• makes a population grow large

• provides geographical boundaries for migration

• helps organisms adapt to abiotic factors

• stops a population from growing large

An environmental factor such as predation, disease, and competition that depends on the number of members in a population per unit

• population growth rate

• density- dependent factor

• density- independent factor

• dispersion

An environmental factor such as storms and extreme heat or cold that affects population regardless of their density

• population density

• dispersion

• density- independent factor

• density- dependent factor

When a population has reached carrying capacity

• Growth & Immigration are greater than Death & emigration

• Growth & Immigration are less than Death & emigration

• Growth is exponential

• Growth & Immigration are equal to Death & emigration

What two factors are attributed to population decline?

• increase Birth rate & increase Death rate

• Immigration & increase Birth rate

• increase Death rate & increase Emigration rate

• Emigration & Immigration

What is the carrying capacity of the following graph?

• 600

• 800

• 1000

• 1200

Will competition increase/decrease the carrying capacity of an ecosystem for the animal in competition?

• Decrease

• Increase
