Sustainability is making sure that the planet and its resources can continue to provide life.
True
False
An accurate definition of Sustainability is
meeting population needs
meeting the needs of the present without compromising the ability of future generations to survive
meeting the needs of the future without worrying about todays
meeting the food needs of animals
TRUE or FALSE? Invasive species grow quickly due to the lack of predators. This leads to a decline or extinction of the native population.
True
False
A species that is not native to an area is called a ---
Native Species.
Natural Species.
Invasive Species.
Symbiotic Species.
Why do the populations of invasive species grow so quickly?
Invasive Species are native to an area.
Invasive species are prey to many animals.
Invasive species have no predators.
Invasive species keep the ecosystems in equilibrium.
The primary cause of the introduction of invasive species introduction is ---
too much food.
human action.
weather events.

Click on the map to help answer this question. What can we predict about the population of Feral Swine for the year 2016?
There will be less feral swine in 2016 than there were in 1982.
There will be more feral swine in 2016 than there were in 2010
There were fewer feral swine in 2004 than 1982.
There will be no change in feral swine population.
A native species is
a species that lives in the region where it evolved.
a species that came from ancient ecosystems
a species that can out produce other species
a species that was brought to a region by people
Who is at the most risk of going extinct?
large population
genetically diverse population
few harmful mutations
small population
A species form that supports an entire ecosystem.
Keystone Species
Herbivores
Umbrella Species
Predators
Why are bees considered a keystone species?
The honey they make supports the bear population
They pollinate flowers that produce fruit which supports the ecosystem
They sting when threatened
They live in hives
Species that are clearly critical to the functioning of an ecosystem are known as
biodiversity
keystone species
main species
native species
Succession that occurs in areas that previously didn't support life, such as on rocks or ice
tangential succession
primary succession
secondary succession
quaternary succession
A common type of succession that occurs where an event such as a forest fire has occurred, or a farmer's field has been abandoned is called
common succession
primary succession
secondary succession
Quaternary succession
Which of the following forms of biodiversity describes all of the different types of biotic factors in an ecosystem?
Species Diversity
Habitat Diversity
Genetic Diversity
None of the Above
Which of the following forms of biodiversity describes the differences between individuals within the same species?
Species Diversity
Habitat Diversity
Genetic Diversity
None of the Above
Why is biodiversity in an ecosystem so important?
Because it can help humans where to determine good places to develop farm land.
Because places that have a healthy biodiversity are unaffected by major disturbances.
Because having a high biodiversity allows ecosystems to withstand major changes.
Because having a high biodiversity allows for fewer opportunities of competition for similar resources.
The largest number of individuals that an environment can support long term is...
carrying capacity
emigration
immigration
population density
What happens if a population grows past its carrying capacity?
The population keeps growing
The population starts to die off
The entire species will go extinct
The carrying capacity just increases
This may cause a population to increase
increase of food supply
removal of predators
removal of disease
all of these
Something that regulates the size of a population is called...
