100
What is:
an extreme increase in the number of species in a population
population explosion
100
data showed that all three populations were stable.
Then the penguin population decreased suddenly. What will likely happen to the size of the sardine population as a result?
increase.
The smaller penguin population will need fewer energy storage molecules, so they will eat fewer sardines. This will lead to fewer deaths than births in the sardine population.
100
When two or more populations use the same resource, such as the same food source, we say there is __________________.
a. cooperation
b. fighting
c. competition
d. cannabalism
c. competition
100
What kind of blood type is known as the universal donor?
O negative.
200
What is:
All the living and nonliving things in a particular area?
Ecosystem
200
the sizes of the populations have been stable for the last 6 years, but recently the size of the wolf population increased.
What will likely happen to the coyote population?
decrease.
Fewer energy storage molecules will be available to the coyote population from the smaller deer population, so the coyote population will reproduce less. This will lead to fewer births than deaths in the coyote population.
200
When one population eats organisms from another population, we say that they are the _____________ _____________.
a. top dog
b. producer population
c. consumer population
d. animal canibal
c. consumer population
200
What kind of animal is an Orca?
whale
300
What is:
A molecule that organisms can use to release the energy needed to survive
energy storage molecule
300
The sizes of the populations have been stable for the last 10 years, but recently the size of the frog population decreased.
What will likely happen to the spider population?
increase.
More energy storage molecules will be available to the spider population from the larger fly population, so the spider population will reproduce more. This will lead to more births than deaths in the spider population.
300
What do we call a particular area where organisms interact with each other and their physical surroundings?
a. population
b. ecosystem
c. city
d. environment
B. Ecosystem
300
What phenomena keep the planets in orbit around the sun?
Gravity
400
What is:
A scientist who studies the interactions of organisms with each other and their environment
Ecologist
400
The data showed that all three populations were stable.
Then the grasshopper population decreased suddenly.
What will likely happen to the size of the rat population as a result?
decrease.
The smaller grasshopper population provides fewer energy storage molecules for the rat population, so the rat population will reproduce less. This will lead to fewer births than deaths in the rat population.
400
A population of sharks lives in the Atlantic Ocean. Over the last 50 years, the size of the shark population increased. What best explains the increase in the size of the shark population?
a. A lot of sharks were born and no sharks died.
b. The shark population is always increasing because no animal eats sharks.
c. More sharks were born than died.
d. Fewer sharks were born than died.
C. More sharks were born than died.

- animals
-plants
-soil
-light from the sun
-animals -plants -soil -light from the sun
500
The data shows that recently the shark population increased.
How will the increase in the shark population affect the other populations?
There will be more deaths than births in the sea otter population so the size of the sea otter population will decrease
This would lead to a decrease in the size of the sea otter population.
The smaller sea otter population would need fewer energy storage molecules from its resource population, so there would be fewer deaths in the clam population.
This would lead to an increase in the size of the clam population.
The smaller sea otter population would also cause the size of the sea star population, which competes with the sea otters for clams, to increase because there would be more energy storage molecules available for the sea star population.
500
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. A lot of deer died and no deer were born.
b. Fewer deer were born than died.
c. The deer population is always decreasing because deer are always being eaten.
d. More deer were born than died.
B. Fewer deer were born than died.

Hydrogen and Oxygen.
