Part 2) Complete the ecological footprint quiz at the following link:http://myfootprint.org/en/visitor_information and report your results. What did you learn about you and your family's impact on the environment? 2. The result that I got was 4.93 Earths would be needed if everyone on the planet lived my lifestyle. I didn’t realize how inconsiderate I was until I took this quiz. Now that I actually saw what my habits are doing to the environment I am going to start recycling and using energy savings products.
Exercise 2. Using ONE ecosystem from the list below, explain the role of the carbon, hydrologic, phosphorus, and nitrogen cycles in this ecosystem.
Choose from a "normal": tropical rain forest, tundra, river delta, or savannah
The importance of rainforests in the carbon cycle depends on the extent of the forest, the amount of carbon stored per unit area and the rate at which carbon is fixed by the plants during photosynthesis. Plants and animals contain a great deal of carbon, which they take up as carbon dioxide during growth and photosynthesis, and which they release to the atmosphere during respiration and decomposition. The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration. Humans can alter the phosphorus cycle in many ways, including in the cutting of tropical rain forests and through the use of agricultural fertilizers. Rainforest ecosystems are supported primarily through the recycling of nutrients, with little or no nutrient reserves in their soils. Nitrogen is one of the key nutrients required by the flora. Humans have
