of disorder in a system • Entropy increases Energy Gained Energy Lost With each conversion‚ there is a one-way flow of energy back to the environment Sunlight energy reaches Earth. Producers secure some and convert it to stored forms of energy. They and all other organisms convert stored energy to forms that can do cellular work. Energy Lost Free Energy • It takes energy to break chemical bonds • Free energy – energy available to do work in any system • Endergonic reactions

b 1 Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally

What factors most strongly influence the type of biome that forms in particular place on land? What type of factors determines the type of aquatic system that may form in a given location? The two factors that strongly influence the type of biome on land is the temperature and the precipitation. The type of factors that strongly influence aquatic systems is water temp‚ salinity‚ dissolved nutrient’s‚ wave action‚ currents‚ depth‚ and substrate. Ch. 6 p. 376 1. What is the approximate climate
