Textbook Question
Chapter 3, Problem 15IMT
For each statement, identify which major theme is evident (the relationship of structure to function, information flow, pathways that transform energy and matter, interactions within biological systems, or evolution) and explain how the statement relates to the theme. If necessary, review the theme descriptions (see Chapter 1) and review the examples highlighted in blue in this chapter.

Q1: What source of energy would plants use for anabolic reactions? Would an animal use the same kind of energy? Q2: What source of energy would plants release in catabolic reactions? Would an animal release the same kind of energy? Q3: Create a mnemonic or jingle that helps you remember the difference between anabolism and catabolism.
Starting as a lipid in some holiday prime rib, trace the path that energy and biomass make as that lipid is consumed by a college freshman, transported to a cell in the liver and converted into a carbohydrate, and finally as that carbohydrate is burned for energy in a cell in the cells of the shoulder muscles. Following your diagram/model, provide a written explanation for what you diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand cellular respiration and the movement of mass and energy in animals.
note;please include about the energy lost as heat

As scientists research and develop biofuels, they are faced with many tradeoffs. A plant's usefulness for biofuels depends on how much energy can be collected from the plant matter. In addition, growing plants on a large scale requires energy—such as the gasoline and power needed to run tractors and other harvesting equipment or the energy needed to create and distribute fertilizers and pesticides. An efficient biofuel would maximize the ratio of energy output to energy input.
The following graph illustrates the results of a 10-year study analyzing three different crops used in biofuel production. The data show how much energy was required to grow each crop on 1 hectare of land (energy input) and how much energy was recovered from the total crop on each hectare of land (energy output). A hectare is a measurement of an area of land and is roughly the same as 2.5 acres.
What was the estimated energy input of the grass?
A. 2 kcal × 106
B. 4 kcal × 106
C. 8 kcal…
