many types of animals
What is the best definition of an organism?
Many individuals of the same species living in the same area.
All of the living and nonliving things in a particular area.
An individual plant, animal, fungus, or single-celled life form.
A creature that is large enough to see without using a microscope.
Which picture accurately shows a "population"?
What causes a population size to increase?
The number of births is greater than the number of deaths.
The number of deaths is greater than the number of births.
The number of births and the number of deaths is equal.
What causes a population size to decrease?
The number of births is greater than the number of deaths.
The number of deaths is greater than the number of births.
The number of births and the number of deaths is equal.
If the population size stays stable, does this mean that no organisms have been born or died?
Yes, because if organisms were born or died that would change the number of organisms in the population.
No, because if some organisms are born and the same number of organisms die, then the total population size can stay constant.
Yes, because some organisms never die, so they don't need to reproduce.
No, because all organisms will give birth and then die.
Based on this graph, what must be true about the US honeybee population?
There are more births than deaths occurring.
There are more deaths than births occurring.
There is an equal number of deaths and births occurring.
People don't like honeybees.
A large population of squirrels lives in a forest. In the last 50 years, the size of the squirrel population has stayed the same. What must be true about the squirrel population during the last 50 years?
No squirrels were born and no squirrels died.
Humans started protecting the squirrel population so they stopped dying.
The squirrels did not have any baby squirrels during these years.
The number of squirrels that were born was the same as the number of squirrels that died.
A population of tigers lives in Bangladesh. Over 50 years, the size of the tiger population increased. What best explains the increase in the size of the tiger population?
A lot of tigers were born and none of them died.
The tiger population is always increasing because no animal eats tigers.
Fewer tigers were born than died.
More tigers were born than died.
A population of bluefish lives in the Gulf of Mexico. Over the last 50 years, the size of the bluefish population has decreased. What best explains the decrease in the size of the bluefish population?
A lot of bluefish died and no new bluefish were born.
More bluefish were born than died.
Fewer bluefish were born than died.
The bluefish population is always decreasing because bluefish are always being eaten.
A large population of ducks lives in an area with a lake. In the last 40 years, the size of the duck population has stayed the same. What must be true about the duck population during the last 40 years?
The number of ducks that were born was the same as the number of ducks that died.
No ducks were born and no ducks died.
Humans started protecting the duck population so they stopped dying.
The ducks did not have any baby ducks during these years.
A population of mice lives in the northeastern United States. Over the last 50 years, the size of the mouse population decreased. What best explains the decrease in the size of the mouse population?
Fewer mice were born than died.
A lot of mice died and no new mice were born.
More mice were born than died.
The mouse population is always decreasing because mice are always being eaten.
A population of deer lives in Canada. Over 50 years, the size of the deer population decreased. What best explains the decrease in the size of the deer population?
A lot of deer died and no deer were born.
Fewer deer were born than died.
The deer population is always decreasing because deer are always being eaten.
More deer were born than died.
When a populations is known to be STABLE, it:
there are more deaths

stays mostly the same, over time
horses live there
True or False: Nonliving and dead mean the same thing.
