Population Ecology

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.

Largest number of individuals of a population that the environment can support...  

• carrying capacity
• population crash
• lag phase
• mutualism

What is the carrying capacity for this sheep population?

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

When a population grows past the ecosystem's carrying capacity, what happens to the population?

• Continues to grow
• The population starts to die off to return to carrying capcity
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity

Food, water, sunlight, shelter, and space are resources that are often __________.

• limiting factors
• wet
• messy
• found in rocks

In a forest ecosystem, which of the following is the best example of a limiting factor for a rabbit population?

• Squirrel Population
• Sunlight
• Grass available

When organisms move out of the population, this is known as

• emigration
• abandonment
• immigration
• succession

which statement sounds accurate based on the graph data. 

• The zebra and lions do not affect each other
• when lions population increases, so does the zebra population
• When the zebra population increases, it causes the lion population to also increase
• when zebra populations go down, the zebra population goes up. 

Which kind of growth does the human population follow? It is described as a J-shaped curve.

• Exponential Growth
• Logistic Growth
• Outstanding Growth
• Minimal Growth

A population is...

• A group of one species in one area
• Multiple species that live in one area
• All of the living and nonliving things in an area
• None of these
