Copyright © 2024 SlideSpark LLC Flow Organisms need energy to survive. Energy from the sun flows into and out systems. This energy drives our world and the organisms in it. Energy is lost “not destroyed” when it changes form. Flows Hot to Cold Levels Ecological systems are organized within each other. The affects on one system will affect them all. All systems are interconnected. Change All organisms are in a constant state of change over time with the environment. Some organisms will change with another and will develop special interactions. Others with the nonliving world. Matter and energy cycle through the living and nonliving world. Organisms rely on this matter and energy cycling to survive. Animals are interconnected in a complex web of life. Changes on one part of the web have will effect other parts of the web and the stability of the entire ecosystem. Cycles WEB Balance Ecosystems have a way to balance changes so that up and down fluctuations are part of the natural balance of the whole.
