Document Summary

Allows you to be an informed science citizen. Enriches appreciation of the earth and its inhabitants. Organisms acquire and use materials and energy. Organisms have the collective capacity to evolve. Non- living things may possess some of these characteristics. But only living things can do it all. Obtain material that make up their body, such as minerals, water and other simple chemical building blocks from; air, water ,soil from bodies of other organism. Materials are continuously exchanged and recycled among organisms and surroundings. Energy is required to move and to construct the complex molecules that make up an organisms body. Organisms tend to disintegrate into chaos unless energy is used to maintain it. Organisms must use energy to maintain themselves. Membrane pumps some chemicals in and others out. People and mammals use energy to keep internal organs a t a warm constant temp that allows the proper reactions to occur in their cells.
