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

It will fluctuate.

It will decrease.

It will stay the same.

It will increase.

The number of organisms per certain area

carrying capacity

total population

population density

When organisms move out of a population it is known as

emmigration

immigration

Increases in lion populations cause zebra populations to increase

When zebra populations decrease, the lion populations increase

zebra and lion populations do not affect one another

When zebra populations increase, lion populations then increase as well

A population is defined as
