Single celled organisms, like bacteria, are extremely small, independently-living organisms with a cellular structure. DNA has a massive job of keeping you alive. Endocrine Homeostasis and Integration of Systems, 59. Atoms are made up of subatomic particles such as the proton, electron and neutron. The Chemical Level of Organization, Chapter 3. The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism. 3. All the different populations that live together in an area. Some organisms, such as bacteria or yeast, are unicellularconsisting only of a single cellwhile others, for instance, mammalians, are multicellular. The body is made of many different cell types, each with a particular function, (for example muscle cells contract to move something, and red blood cells carry oxygen). ___________________ are characterized by chemical cycling and energy flow, What is the term for: the zone of air, land, and water where life is found. species, genus, family, order, class, phylum, kingdom, domain, Name the kingdom that fits with the following description: Ecosystems are organized to better understand the frame of reference in which they are being studied. Higher levels of organization are built from lower levels. What are the 7 characteristics of living things? An organ system is a group of organs that work together to perform specific bodily functions. Higher levels of organization are built from lower levels.
