Examples: Cell: An egg Tissues: Muscle An organ: skin Organ System: The digestive system Organism: Us! Population: Ladybugs Community: fox, flowers, trees Ecosystems: rivers, trees, foxes, flowers

Summary: · The cell is the smallest unit of life on Earth. Organisms can be made up of one or more cells. · In multicellular organisms, groups of cells can work together to form tissue. Organs are formed from different tissues and work together with other organs in organ systems. · The same kind of organisms living together in the same place at the same time makes up a population. Different populations living together in the same area make up a community. An ecosystem includes a community and an area’s non-living parts, such as water and soil. This is a muscle tissue. It's made of cells working together. Human oranisms have tissues like muscle, fat, and red blood cells.http://www.google.com/imgres?imgurl=http://www.arthursclipart.org/medical/humanbody/muscle%2520tissue.gif&imgrefurl=http://www.arthursclipart.org/medical/humanbody/page_01.htm&usg=__zlnLrTVHyUKU8eLayZrdKNEdb_4=&h=650&w=1401&sz=490&hl=en&start=0&zoom=1&tbnid=a1eQO03amEAv9M:&tbnh=71&tbnw=153&ei=WqtnTfrwOcWclgfF3NGBAg&prev=/images%3Fq%3Dmuscle%2Btissue%26hl%3Den%26safe%3Dactive%26biw%3D1003%26bih%3D415%26gbv%3D2%26tbs%3Disch:1&itbs=1&iact=rc&oei=WqtnTfrwOcWclgfF3NGBAg&page=1&ndsp=10&ved=1t:429,r:1,s:0&tx=105&ty=36

This is an example of an ecosystem.A tree effects humans, animals, bugs and other plants. Whenm these things affect eachother it creates an ecosytem. []

Some great links are below! This website is great for examples! A teacher made it for her 7th grade class! [] This site tells you exactly what the organization of life is! It's in order too! []

This is a catchy video to help remember the order of the organization of life. Ignore the part about biospheres! media type="youtube" key="1ip5Dm7MZyc" height="390" width="640"
