a population that eats organisms from another populations
TRADE POINTS WITH ANOTHER TEAM (OPTIONAL)
consumer population
A population of panthers lives in the southeastern United States. Over 50 years, the size of the panther population in the region increased. What best explains the increase in the size of the panther population?
a The panther population is always increasing because no animal eats panthers.
b Fewer panthers were born than died.
c More panthers were born than died.
d A lot of panthers were born and none of them died.
c More panthers were born than died.
when two or more populations of animals use the same resources
Competition
organism that is hunted and eaten by another organism
Prey
More deaths than births
3x POINTS
Population size decreases
Population that is eaten by other populations
resource population
If there is an increase to a predator's population, what will likely happen to the prey's population size?
Decrease
T or F: A whale, a coral reef, a jellyfish, and a seagull can all be part of an ecosystem.
True – These are all part of marine ecosystems. Whales, jellyfish, and seagulls interact with coral reefs in oceanic environments.
Process of creating offspring
DOUBLE JEOPARDY= DOUBLE POINTS
Reproduction
Same number of births and deaths
DOUBLE JEOPARDY
Population size stays stable
when a population stays the same over a length of time
stability
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.
Plants make their own food through this process
Triple Points !!!
Photosynthesis
Organisms can use this to release the energy they need to survive
Steal Points From Another Team and Add them to yours ( Optional)
Energy storage molecules
Organisms in consumer populations get energy storage molecules from eating organisms in ____________ __________.
STEAL POINTS
Resource populations
All the living and nonliving things interacting in a particular area
Ecosystem
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?
a The number of squirrels that were born was the same as the number of squirrels that died.
b Humans started protecting the squirrel population so they stopped dying.
c The squirrels did not have any baby squirrels during these years.
d No squirrels were born and no squirrels died.
a The number of squirrels that were born was the same as the number of squirrels that died.
What happens to a population in competition if the other population size decreases?
It will increase
when 2 organisms are fighting for the same resources (such as food)
Competition
Two populations compete for the same resource. If one population gets bigger, it ______________________________________.
A. Gives both populations more resources
B. Lowers the amount of competition
C. Can leave fewer resources for the other population
D. Has no effect on resources
C. Can leave fewer resources for the other population
In a forest ecosystem, wolves hunt deer, and deer eat plants. If the wolves are removed from the forest, how might this change the number of plants? Explain how the removal of wolves could indirectly affect the number of plants and deer population.
DOUBLE JEOPARDY POINTS
The indirect effect is that without wolves, the deer population may increase because there are fewer predators. As the number of deer increases, they will eat more plants, causing the plant population to decrease.
If the resource population decreases, what will likely happen to the population size of the consumer?
Decrease
What do birds such as eagles and hawks need energy for?
a flying
b breathing
c digesting food
d all of the above
d all of the above
