Part 1:Then write a two to four page position paper: Is the Three Gorges Dam doing more good than bad?Part 2: Answer the following questions using 2-3 sentences.1. In what ecosystem province is Charleston, SC?2. What is the predominant land-surface form in this province?3. What is the moisture deficit?4. What are the indicator species?5. From what ecosystem province do you come?6. If you were to walk NW from Charleston and arrive at the Great Lakes, through what ecosystem provinces would you pass?7. What is the difference between an ecosystem and a biome? Why might someone find it more useful to use the concept of ecosystem or ecosystem provinces as shown here? Describe a situation in which it might be more useful to use the concept of biomes.

plant in ________are adapted to grazing and periodic fires 1- desert 2- tropical rainforest 3- grassland 4- boreal forest

Why do most forested ecosystems tend toward a long-term, “sustainable” level of soil organic matter?

It’s not answer choice D

The benthic zone is home to organisms which are     photosynthetic.     intertidal.     heterotrophic.     adapted to high light.   Some ecosystems develop a vertical structure (such as seen in a tropical forest). The cause of this is due to competition for which resource?      nitrogen     minerals     moisture     carbon dioxide     light   The biome that is characteristic of Bronx County is a     taiga.     temperate deciduous forest.     temperate rain forest.     desert.     coniferous forest.

To discuss: The ecosystem services of forests and describe the consequences of deforestation.

Which variable is MOST important for determining whether a forest will have an open or a closed canopy? Intensity of solar radiation Temperature Water availability

The ecosystem of a lake or pond can be divided into 3 zones. Which zone is very cold and consists of the dead remain of organisms?

DRAW IT (a) Draw a simplified global water cycle showingocean, land, atmosphere, and runoff from the land to theocean. Label your drawing with these annual water fluxes:ocean evaporation, 425 km3ocean evaporation that returns to the ocean as precipitation,385 km3ocean evaporation that falls as precipitation on land, 40 km3evapotranspiration from plants and soil that falls as precipitation on land, 70 km3runoff to the oceans, 40 km3(b) What is the ratio of ocean evaporation that falls as precipitationon land compared with runoff from land to the oceans? (c) Howwould this ratio change during an ice age, and why?
