Question 1
Part A
A- Color. Dissolved matter and may decrease light diffusion.
B- Odor. Presence of cholrine and specific to smell.
C- Carbon Dioxide. Increase is a decrease in pH and Decrease is a decrease in photosynthesis.
Part B
A- Because of the amount of chemicals in pollutant in the water, the distribution of insect larvae is not the same.
B- One variable that we will test in our water is pesticides.
C- Test and record data and repeat experiment for accuracy four times.
D- There are different amounts of pesticides in each water which prevents growth
Part C
An indicator species is a species whose presence or absence serves as an early warning sign or environmental change and degradation of a natural community.
Example: E. Coli. More warm blooded animals with a lower intestine will be found.
Question 2
Part A
A renewable resource is a resource that is not depleted my moderate use and is replinesed by a natural process.
Example: Solar and wind energy
A nonrenewable resource is one that is not relished by natural process but exists in a fixed amount and takes a long time to replenish.
Example: fossil fuels, oil coal and natural gas
Part B
More developed nations use more nonrenewable resource than developing because they need the energy to run businesses and etc. In developed countries there is a higher standard of living per capita because of electricity and cars. Developing countries don’t have cars so no energy needed and etc. Developed countries buy excess while developing buy only what they needed.
Part C
Sustainable resource use is the use of a resource at a rate that does not reduce its availably or its ability to be replenished for a long term basis.
Example: Fish harvest must leave enough breeding stock to renew the species and prevent extinction. We could limit fish seasons and regulate the type of fishing gear used.
Part D
Economic policies to facilitate include increasing the tax on a virgin resource to discourage its use and to impede it would be decreasing the tax on that virgin resource to encourage its use.
