True/False: Within a populations organisms are always being born or dying.
True/False: Populations can never compete for the same food.
FALSE
What bus line did we take for the Exploratorium?
9 or 9R
A population of tigers is increasing. What does this mean?
There are more births than deaths.
the process of creating offspring
reproduction
The more energy storage molecules available to a population,
the more the population can reproduce
How would an increase in the sea turtle population affect the zooplankton?
More sea turtles means increased predation on moon jellies. Less moon jellies means less predation on zooplankton so the population would increase.
What two teams does Mr. Flores always root for?
Warriors and Giants
Over 50 years, the size of the deer population decreased. What is the best explanation as to why that happened?
Draw an example of a food web.
If the number of births and deaths in a population are equal, the population is ___________ .
STABLE
Moon Jellies and Walleye Pollocks competed for the same resource. What would happen in the Walleye Pollocks were overfished?
The Zooplankton population would increase because there are less predators. That means Moon Jellies would have more to eat, more ESMs, increased reproduction and increased population because of more births than deaths.
How many TK-8 classrooms are in Mission Prep?
19 - 1 TK and 2 for all other grades (K-8)
In Australia, both opossums and foxes eat rats. The sizes of the populations have been stable for the last 12 years, but recently the size of the opossum population increased. What will likely happen to the fox population? Why?
Decrease. Fewer energy storage molecules will be available to the fox population from the smaller rat population, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.
when two or more populations use the same resource
Organisms in a consumer populations get their energy storage molecules from the _________________.
resource population
In the Sim, the weebug population had two consumers, who were they?
Furbils & Stingwigs
Where did Mr. Tapia go to college for his bachelor's and and master's?
University of California!
Scientists have been studying the size of three populations in a grassland. In this ecosystem, lizards eat fireflies, and fireflies eat gnats (a type of insect). The data showed that all three populations were stable. Then the lizard population decreased suddenly. What will most likely happen to the size of the firefly population as a result? Why?
Increase. The smaller lizard population will need fewer energy storage molecules so they will eat fewer fireflies. This will lead to fewer deaths than births in the firefly population.
What is an ecosystem?
all the living and nonliving things interacting in a particular area
Fill in the blank: More __________ = More ________ = Increased ______________ = Increased _________
In the Sim, to increase the Clawcat population, what needed to happen?
The furbil population needed to increase.
What does Ms. Gusau always have in her hand?
COFFEEEEEEE
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.
