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

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

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.

This graph shows ....

• When one population increases, the other decreases.
