principle and efficacy of wetlands

How do wetlands  help to keep our supply of freshwater clean?

Wetlands offer a diversity of benefits. They provide a habitat for wildlife, spawning grounds for U.S. commercial fish, and renewable timber resources. In the last 200 years, the United States has lost more than half its wetlands. Environmental Almanac gives the percentage of wetlands lost in each state in the last 200 years. For the 30 of the lower 48 states, the percentage loss of wetlands per state is as follows.45518755355924607189683845425093738905083305948355035272742Make a stem-and-leaf display of these data.

Are there any gaps? (Select all that apply.)The percentages are concentrated from 20% to 60%.There is a gap showing that none of the lower 48 states has lost from 10% to 19% of its wetlands.There is a gap showing that none of the lower 48 states has lost from 60% to 69% of its wetlands.These data are strongly skewed left.These data are fairly symmetric, perhaps slightly skewed right.The percentages are concentrated from 60% to 90%.There are no gaps in the data.

What is the purpose of the constructed wetland in remediating surface runoff waterQuestion 2Answera.It controls atmospheric PM2.5b.It is a renewable energy sourcec.It controls water pHd.It is used for waste managemente.It removes sediments and nutrients

The following are impacts on the environment, which can occur as a city continues to grow. Select the method of land-use planning that is most appropriate for the expansion described in this process.  As a city grows, its impact on the environment increases as it sprawls out to a surrounding area that includes a wetland and an adjacent forest. If trees are cut down and plant cover is removed, the soil is left open to erosion and flash flooding. Animals would be forced to move, and may die or face starvation or disease. The loss of wetlands can lead to a decrease in water quality, since wetlands naturally filter water. In addition, the wetlands are an important breeding ground for waterfowl.Use tab to navigate through all the objects.
