Births/Deaths
If the number of births and deaths in a given time are equal then the population size will be _____.
stable
What is energy?
The ability to make things move or change
a model that shows what eats what in an ecosystem
food web
What is Ms. Villarreal's dog's name?
Chubbs
If there are more births than deaths in a given time, then the size of the population will _____.
increase
Where do weebugs get their energy storage molecules from?
greenleafs
Which species could directly effect the moon jelly population in the Glacier Sea?
zooplankton & sea turtles
a small part that is meant to show what the whole is like
sample
What do birds, such as eagle and hawks need energy for? Flying, breathing, digesting food, or all of the above?
All of the above.
In the northwestern United States, both coyotes and wolves eat deer. 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
In the yeast experiment, what was the effect of sugar on the yeast?
The more sugar available the more energy there is to reproduce.
What species could indirectly effect the moon jellies population size?
algae, walleye polluck, orca
a molecule that organisms can use to release energy they need to survive
energy storage molecule
What is Ms. Villarreal's biggest pet peeve?
Leaving trash behind.
In an ecosystem, snakes eat rats, and rats eat grasshoppers. 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.
What change to the greenleaf population could decrease the number of births in the weebug population?
decrease greenleafs
What change needs to happen to the orca's population in order for the moon jelly population to increase?
all the living and nonliving things interacting in a particular area
ecosystem
What do mammals, like tigers and zebras need energy for? Running, breathing, digesting food or all of the above?
All of the above?
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?
Name one type of energy storage molecules.
Starch, glucose, fat
What change in the algae population needs to happen in order to increase the moon jelly population?
Increase algae
a group of the same type of organism living in a particular area
population
What is Ms. Villarreal's favorite video game?
Animal Crossing: New Horizons
