All of the above.
What was the effect of wolves being reintroduced to Yellowstone?
Biodiversity increased
Biodiversity decreased
Biodiversity stayed the same
Biodiversity is not a real word
What are the dangers of an ecosystem lacking diversity?
Ecosystems are living structures and biological diversity provides stability.
A single change (physical or biological) could affect entire populations.
Neither A or B
Both A. and B.
What is the difference between "venom" and "poison?"
Venom is injected. Poison is absorbed, ingested, or inhaled
They both can be the same. Only the method of introduction to the body differs.

Don't use chemical pesticides on crops.
All of the above
“Population” can be defined as:
Groups of individuals belonging to the same species that live in the same region at the same time.
An interacting group of various species in a common location
The number of organisms an ecosystem can sustain.
The variation of structures that provides a healthy stabilizing effect on an ecosystem.
Which of the following examples could be considered an “invasive species?”
An oxpecker eats the bugs and parasites off a zebra.
Clownfish live amid the tentacles of the anemones which protects them from predators.

To support the claim that the consumption of natural resources by humans has a negative impact on the environment, what kinds of data would be needed to provide evidence?
Increasing human life span over time and global increase in sea level
Increasing human population and decreasing size of habitats for plants and animal
Increasing the consumption of resources by humans and increasing biodiversity
Increasing burning of fossil fuels by humans and decreasing use of other resources
This graph presents data on the amount of land used by a certain city each year to bury solid waste. In the year 2000, the city started a recycling program to slow the increase of land needed for this purpose. What data would support the claim that this program effectively achieved its goal?
Data showing that by the year 2010, more than 40% of the citizens were participating in the recycling program
Data showing that the land used for burying solid waste in 2010 was less than 22 square kilometers
Data showing that by the year 2010, there was five times more solid waste being buried than being recycled
Data showing that the land used to build a recycling facility is greater than the amount of land used to bury solid waste
The fertilizers that farmers use to improve the growth of crops can result in excess nitrogen in water that flows into ponds and lakes. This sometimes results in a rapid growth of algae, called an algal bloom, killing fish. What data might be collected to monitor the amount of excess nitrogen in local water systems?
The rate of crop growth
The size of ponds and lakes
The frequency of algal blooms
The kinds of fish that eat algae
People move into and begin living in an area that previously had no human activity. What will most likely be the effect on the amount of water?
Water will be more evenly distributed in the area.
Most of the fresh water in the area will be converted to salt water.
The amount of fresh water suitable for drinking will increase.
There will be less available for other living things.
