Population Dynamics

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

• Stays the same

• Increases

• Decreases

• Fluctuates

______________ is all of the living and nonliving things in a given area.

• a population

• a community

• an ecosystem

• the biosphere

Anything that restricts the size of a population is a ________________________.

• biotic potential

• carrying capacity

• species

• limiting factor

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.

If the number of births is greater than 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 is the carrying capacity for this sheep population?

• 1.8 million
• 1.25 million
• 1.6 million
• 1.o million

At what population was carrying capacity met?

• 250

• 1000

• 400

• 720

Exponential population growth can be described as

• growth when resources are limited

• a j-shaped curve

• a s-shaped curve

• growth that reaches carrying capacity

Logistic population growth can be described as

• growth when resources are limited

• a s-shaped curve

• reaching carrying capacity

• all of the above

What limits Population Growth?

• birth rates increasing

• resources being used up

• natural selection taking place

• none of the above
