Document Summary

Energy can be changed from one form to another. When energy is changed from one form to another, some is degraded into heat. Heat is a less usable form of energy. Decrease entropy: requires work = energy input. Omnivores - eat both meat and plants. Break down dead organism and waste products. Energy passes from one organism to the next. Trophic level: each step in this ow of energy. The solar energy assimilated by plants is called their gross primary production (gpp) Subtract from this gpp the fraction that the plant uses for itself (respiration) what"s left is called net primary production (npp) Npp gives us a rough yardstick to compare the productivity of different types of ecosystems. A fundamental measure, but also a vague one net primary production (npp) is a term used rather liberally for growth/carbon xation which is available to other organisms.

Kinetic energy differs from chemical energy in that

a. chemical energy is a particular form of kinetic energy.

b. kinetic energy depends on the movement of atoms, whereas chemical energy depends on the movement of molecules.

c. kinetic energy is the energy of a moving object, whereas chemical energy is the potential energy of molecules.

d. kinetic energy is stored energy that has the potential to do work, and chemical energy is the energy of movement.

e. kinetic energy can be converted into various forms of energy, whereas chemical energy can only be converted into heat.

2)What code would you add if you wanted to change it so that the user was able to continue entering a filename until the method initialize InventoryFromFile could successfully be exceuted? (e) Suppose I have the following class definition: 1 1/A TelevisionShow is a new type that consists of a String) for the actors |/ /a String for the name, and a string for the network public class Television Show private String[] actors; private String name; private String network; //this method will return whether or not the property //actors contains actor Name or not public static boolean hasActor (String actor Name) for (int i-0; i < actors.length; i++) { if (actors[i].equals (actorName)) { return true; return false; Unfortunately, when I try to compile this code, I get the following error: Television Show.java:11: non-static variable actors cannot be referenced from a static context for (int i=0; i < actors.length; i++) { Television Show.java:12: non-static variable actors cannot be referenced from a static context if (actors[i].equals(actorName)) { 2 errors What does this error mean and how can I fix it?
