The side of Malaquez's parcel gave way to reveal a greenmunk caught in a sheen of solid air. Bits of leaf mold flew from under his feet as he ran to greet a friend or a bringer of food. Tasha oohed in awe. I said, "Frodo's been visiting you, eh?" Malaquez said, "Your pet?" "Hardly. He lives around here somewhere. I suppose he was attracted to the commotion up the hill." "Ah," Malaquez said. "Why 'Frodo'?" Tasha said, "A little fellow with big, furry feet. What else could he be called?" She handed the sculpture to me. I almost dropped it; I expected it to weigh no more than a holo. "Heavy," I said, as if he might not have known. He laughed. "My last piece was of four old Undersiders crouched around a trash fire. Be glad someone didn't toss that to you." He spoke of his art with the enthusiasm of a seven-year-old. "Um, I should wait to importune you, but..."

Where does Frodo get his name?

Above were just a few things that caused habitat loss or change. There are many ways in which living organisms can affect their ecosystem. In some areas, it is because of fire management. Fire is a natural event, so managing fire correctly is very important. In other areas, fisherman have taken too many fish from one area. This places the species at risk of extinction. It also affects other living things that may rely on these fish for food. The image below shows a picture of a mine. Mining changes the Earths surface. This area may once have been a forest or a prairie. Think about how many plants and animals may once have lived here. Now it is a giant hole in the ground. Pollution is also a major factor in habitat loss and change.

How does mining change the earth's surface?

Mechanical energy is a combination of the energy of motion or position. This type of energy describes objects that are moving or could move. A moving ball can have energy from motion. An arrow can also have the energy of motion. Both are types of mechanical energy. Can you think of some other examples? Where does the energy of motion come from? It comes from the energy created by position. This energy is stored energy. This means it is not moving yet, but it has the potential to move. How can you store energy? The arrow gains energy from the drawn bow. As the arrow is released, the bow releases its stored energy and puts the arrow into motion. Can you think of some other ways to store energy using position?
What type of energy do a moving arrow or ball have?
