ExplanationThere are 13 levels of organization. In sequence, they are represented as atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, population, community, ecosystem, biome, and biosphere. Yes, Watch the entire thing... Match Match the Level of Organization with the correct description Atom The smallest unit of matter Molecules Two or more atoms joined together Organelles A membrane-bound structure in a cell that performs a special function Cells The smallest unit of life that can replicate independently. Match Again! Tissue A group of same cells acting together to perform specific functions Organ A group of tissues working together to perform a specific function Organ System A group of organs working together to perform a specific task Organism An individual living thing, such as a bacterium, plant or animal Seriously? There's more?? Population A group of individuals of the same species living in a specific area Community All the living a things in a specific area Biome A large region of Earth that has a certain climate and certain types of living things Ecosystem A large community of living organisms (plants, animals and microbes) in a particular area. Biosphere The layer of the planet Earth where life exists Biome: Conditions (and not just space) that are suited to a group of communities (plants, animals, microbes, etc.).Organ: Examples in animals include lungs, brain, liver, etc., whereas roots, stem, and leaves are the different types in plants.Molecule : The formation of chemical bonds between two or more atomsTissue: This level is a combination of different types of cells which perform specialized functionsOrganelle: A few examples include nucleus and chloroplasts (plant cells), and golgi bodies and mitochondria (animal cells).Population : A group of organisms which belong to the same species.Organ System: Organs working together to perform certain functions. Examples are the circulatory system in animals, and the vascular system in plants.Organism: the fully functional form of a living being that can thrive in a particular environment.Biosphere: The place, area, and zone where the entire life on Earth exists.Cell: It is considered as the basic unit and building block of life. It is bound by a cell membrane, and possesses a nucleus which acts as its brain.Community: Two or more populations togetherEcosystem: An area or environment, where one or more communities can thrive and flourish.Atom: It is the most basic and fundamental unit of matter. A region of the earth's surface with a specific climate where only certain types of plants and animals live. Ex. Tundra Biosphere Biome Atom Tissue All of the living things (biotic) and the non-living factors (abiotic) in the same place at the same time. Ex. All of the green algae, sunfish, frogs in the water, along with amount of salt and temp of water. Biome Ecosystem Population Biosphere Sort it! Animal Cell Cell wall is absent Shape is irregular Chloroplasts are absent Plant Cell Cell wall is present Shape is fixed Chloroplasts are present A single living thing that has all of the characteristics of life. Ex. Dog :Organism All of the different living things (organisms) in the same place at the same time. Ex. The white tail deer, oak tree, and gray squirrels in the forest. : Biome Different organs working together to perform a major process in an organism. Ex. Digestive System : Organ System The smallest part of an element made of protons, neutrons, and electrons. Ex. Carbon (C) : Atom
