What happened to the rabbit population after 2002?
It remained constant as the birth and death are equal

It reached its carrying capacity
It increase because more food became available
The city wants to eliminate one of the two water treatment plants in order to save money. This would then allow water quality to be monitored at only one river in the area. The EPA is concerned this may lower water quality. Why is it important for the EPA to monitor water at all rivers in the area?
Collection of data is not relevant to the city's decision as they will not determine the effect until after the change has been made
Monitoring the environment ahead of time will allow the EPA to evaluate the impact of water quality relying on just one river site
Monitoring water quality before the elimination of testing at area rivers determines the amount of toxic substances the environment can handle
Showing the high water quality before the cutback will support the city's decision as water quality can't deteriorate
Wildlife bridges are pathways that allow wildlife to avoid crossing a highway. A scientist wants to know if the bridges could help an endangered species in the area. How could the scientist best monitor if more wildlife bridges should be built to protect an endangered species?
Look at the total number of deaths of the endangered species before and after the wildlife bridge is built
Count the population after the bridge is built
Use a camera to see if the endangered species use the bridge to avoid the highway
Count the total endangered species population before and after the bridge is built
The relationship between Cheetahs and zebras in Africa depicts the predator-prey relationship. Since the zebras are a main prey of the cheetah, researchers have realized a food shortage as the cheetahs are eating too many zebras. This keeps the cheetah population in check. How does this relationship affect this populations?
The relationship controls the population size of both species
The predator or prey will become extinct
The predator and prey are in competition with each other
The predator species has exponential growth
The graph below shows the results of an experiment where the two populations have a relationship. The first two graphs show the populations separated then the last graph shows them mixed together. What type of relationship do these two populations have together?
P. caudatum is a parasite of P. aurelia
P. caudatum shows commensalism with P. aurelia
P. aurelia shows mutualism with P. caudatum
P. aurelia is a parasite or P. caudatum
Lake Nona had an increase of 10% of their population. As a result the city officials have planned to build more homes, supermarkets, clothing stores, and restaurants. What should the local government consider about the effects of the local ecosystem prior to approving the plan?
The impact of the development on the types of products that will be sold
The type of store that will be present in the commerce center
The risk of a loss of biodiversity in native species
Financial obligations to the developer
What type of relationship is demonstrated by these organisms when living together?
Parasitism
Predation
Competition
Mutualism
In Flint, Michigan, Lead was found in their water as the government officials switched to a toxic water source. Also, lead was used in the plumbing of houses and ended in 2014. Scientists had some concerns with lead poisoning as it caused autism in children and kidney problems in adults. How does the story of lead show the importance of continued monitoring of ecosystems?
Monitoring is not important as long as the product is tested before being released
Monitoring is important to ensure a product does not have unintended consequences on the ecosystem
Monitoring is important to make sure the product is effective
Monitoring is not important because any damage can be fixed
The Florida Panther is an endangered species. Its main food source is the White Tailed Deer. What would happen to the deer population if the panther population decreased in size?
It would increase and then level off
It would not be affected
It would increase
It would decrease
What is an example of an abiotic factor? Check all that apply
Temperature
Animals
Precipitation
Plants
Winter Park has had an increase of 20% in their population last year. As a result, city officials have planned to build a new shopping district. What is the most important consideration the local government should have about the environmental effects prior to approving the plan?
If the builder has considered how to spend the leftover money to help the environment
There doesn't need to be any environmental considerations as long as the plan makes money for Winter Park
If the builder has an evaluation of the overall impact on biodiversity in the area after the shopping district are built
If the builder has checked for endangered species in the area
There has been a significant increase in the native Blue Jay population after Winter Park High School added several bird houses around the school as a community service project. What is are the Blue Jay's relationship with the bird houses?
Shelter was a biotic factor needed for the Blue Jay population to grow
Shelter was a surplus after many generations
Shelter will increase biodiversity among the Blue Jay population
Shelter was limiting factor for the Blue Jay population
