Energy in Ecosystems A kingfisher and a fish are components of an ecosystem. Each organism has role in the transfer of energy and matter within the ecosystem. Within each organism, biomolecules continually change form as they are broken down and rearranged. Energy and matter can change form as they cycle through an ecosystem, but they are not destroyed. 2o Energy and Matter APPLY Starting with the source of energy, order the components to show how energy and matter cycle through the kingfisher's ecosystem. a. aquatic invertebrates d. aquatic plants b. kingfisher e. fish c. sunlight tions and Energy Flow

WRITE ABOUT A THEME: ENERGY AND MATTER Life issolar powered. Almost all the producers of the biospheredepend on energy from the sun to produce the organicmolecules that supply the energy and carbon skeletonsneeded for life. In a short essay (100–150 words), describehow the process of photosynthesis in the chloroplasts ofplants transforms the energy of sunlight into the chemicalenergy of sugar molecules.

WRITE ABOUT A THEME: Energy and MatterDecomposition typically occurs quickly in moist tropicalforests. However, waterlogging in the soil of some moisttropical forests results over time in a buildup of organicmatter called “peat.” In a short essay (100–150 words), discussthe relationship of net primary production, net ecosystemproduction, and decomposition for such an ecosystem. AreNPP and NEP likely to be positive? What do you think wouldhappen to NEP if a landowner drained the water from atropical peatland, exposing the organic matter to air?
A desert ecosystem includes grasses, mice, snakes, and hawks. As you move up the energy pyramid of this ecosystem, each level has energy *blank* than the one below.
In ecological systems, a rough rule of thumb is that when energyis transferred from plants to plant-eaters or from preyto predator, the efficiency is only about 10% (p. 72). Muchof this inefficiency is a consequence of the second law ofthermodynamics. Another way to think of this is that eating 1calorie of material from an animal is the ecological equivalentof eating 10 calories of plant material.Humans are considered omnivores because we can eat bothplants and animals. Our food choices have significant ecologicalimpacts. With this in mind, calculate the ecologicalenergy requirements for four different diets, each of whichprovides a total of 2000 dietary calories per day. How many ecologically equivalent calories would it taketo support you for a year, for each of the four diets listed?

Many people who want to reduce their ecological footprinthave focused on how much energy is expended (and howmany climate-warming greenhouse gases are emitted) intransporting food from its place of production to its place ofsale. The typical grocery store item is shipped by truck, air,and/or sea for many hundreds of miles before reaching theshelves, and this transport consumes oil. This concern over“food-miles” has helped drive the “locavore” movement tobuy and eat locally sourced food.However, food’s transport from producer to retailer, asmeasured by food-miles, is just one source of carbon emissionsin the overall process of producing and delivering food. In2008, environmental scientists Christopher Weber and H. ScottMathews conducted a thorough life-cycle analysis (p. 400) ofU.S. food production and delivery. By filling in the table below,you will get a better idea of how our dietary choices contribute toclimate change. After measuring mass, energy content, and dollar valuefor each…
