Obtain & use energy What is the lowest level of organization? Atomic of Molecular Level - As Molecules come together and interact they form organelles or structures within the cell. What are the 2 types of Cells? Single celled organisms & Multicellular organisms What is the lowest level of life considered alive? Cell How is an organ formed? When two or more tissues work together to perform a specific job. What forms an organ system? When 2 or more organs and or structures work together to carry out functions they form a organ system.

A Chemical energy form, such as starch or sugar by the process of photosynthesis. Plant eating organisms are known as? Herbivores Meat eating organisms are known as? Carnivores What is Metabolism? All the chemical reactions necessary to extract the enrgy stored in food and the chemical reactions that use the energy released to perform the activites of life. ATP stands for Adenosine Triphosphate - It is released in a special molecule during metabolism. This Molecule is able to carry and transport the energy within the cell.

Define Natural Selection. Natural selection refers to the survival of organisms that have an advantage over other organisms. Usually due to genetic changes that allow adaption in the enviorment easier passed to subsequent organisms. What is the flow of energy? Sun->Plants->Herbivores->Carnivores.
