Migrating
Remaining stable
Increasing
Decreasing
Select all that apply: Which of the following are possible reasons for change in population.
Water availability
Disease/Virus
Predator
Human interaction
Where is the Serengeti located?
Near the equator, Africa
Near the equator, Asia
Near the poles, Africa
Near the poles, Asia
Which predator did we use in our study to determine if they affected buffalo populations?
Lions
Tigers
Bears
Oh Mys
Based on our study, which of the following are migratory animals?
Bison
Buffalo
Water buffalo
Wildebeest
Migration can help an organism survive because?
There are no predators on the migration.
They can move based on food availability.
They can travel for the seasons.
Tourism doesn't happen in the same locations as the migration.
In ecology, a landscape is?
The scraping of the land for resources
The interactions in ecosystems
The changing of the land for the bettering of creatures.
Climate change affects on areas.
Carrying capacity can be on graphs by?
Locating the greatest increase
Locating any change
Determining where the line is horizontal
Determining where the line is vertical
Can't be seen on graphs
Two areas have different values of biomass for prey. What might help predators in the area with biomass for prey is greater in value.
More food for the predator
Prey are bigger and easier to catch
Fewer predator compared to prey, less competition.
More predators so easier to reproduce.
Prey density is how many prey in the area. How might this be used to help carrying capacity for predators?
More food for the area
Less food for the area
Larger area to survive in
Less area to have to hunt
How is food related to carrying capacity?
Species survive when they have nutrition and calories to provide energy.
Species survive they aren't migrating
Species survive in smaller areas better.
Species survive in larger areas better
Grasshoppers were applied to fields of land to improve biodiversity. Some sites were successful.
What best choice of features helps with success of grasshoppers?
Site name
Mean Yearly Rainfall, Site area, average biomass of ants
Number of ant hills
Mean size of ant hills
What was the major reason for the decreased populations before 1960 in the Serengeti?
Drought
Food shortage
World War 2
Rinderpest
Which of the following did we study as a keystone species?
Water buffalo
Wildebeest
Lions
Elephants
How did the wildebeest help the Serengeti?
Increased the food supply for the lions
Reduced the chances of hot fires
Moved immunity of rinderpest across the Serengeti
Limit the spread of rinderpest
How did reducing wildfires and hot fires from grasses help the Serengeti?
Limited the spread of human development
Stopped lions from overgrazing
Increased the grasses to give food to grazing animals
Increased biodiversity
The main cause of wildebeest and water buffalo population increase from 1960 to 1975 was?
Increased grazing
More protected lands
Decreased spread of rinderpest
Increased spread of rinderpest
