Consists of all the living things in a particular area together with the abiotic, or nonliving, parts of that environment.AbioticNon-living, may be within or made by a living organism.BioticLiving. Matter is considered ______ if it was ever alive at some point in time AtomSmallest level. The basic unit of matter. Consists of a dense nucleus surrounded by electrons.Choose an answer 1Ecosystem2Population 3Organ4Energy Don't know?

MoleculeSecond level. A chemical structure consisting of at least two atoms held together by a chemical bond.MacromoleculeThird level. Biologically important molecules that are technically polymers.

Example: DNA.

CellFourth level. The fundamental unit of life. Essentially a tiny droplet of water and other molecules enclosed by a fluid "skin" or membrane. The smallest and simplest entity that possesses all the characteristics of life.OrganelleFifth level. Compartments inside the cell that contain specific groups of macromolecules and carry out specific cellular functions. it encloses the DNA within the cell.MicroorganismSixth level. Single-celled life form. Consists of just one cell and include unicellular organisms such as bacteria and protists.TissueSeventh level. Formed when similar cells work together to fulfill the same detailed function.OrganEighth level. Collections of tissues that work together to carry out a common general function. Present not only in higher level animals but also in plants.Organ SystemNinth level. Consists of functionally related organs. Mammals have many.OrganismTenth Level. Individual living entities that survive and reproduce as a unit. For example, each tree in a forest.PopulationEleventh level. Consists of all the individuals of a species living within a specific area.CommunityTwelfth level. Populations can interact with each other in positive and negative ways, and together they form this.EcosystemThirteenth level. Consists of all the living things in a particular area together with the abiotic, or nonliving, parts of that environment.BiosphereFourteenth level. The highest level of organization in living systems. The collection of all ecosystems on Earth. Includes all habitable zones on the planet, including land, soil, and rocks to a great depth in the Earth's crust; water and ice; and the atmosphere to a great height.Emergent PropertiesCharacteristics of a system that are not present in any of its component parts.BiologyThe scientific study of life and is the branch of science that studies living organisms and the way organisms interact with their environments.HomeostasisThe ability or tendency of organisms and cells to maintain stable internal conditions.

NutrientAny matter an organism needs but cannot make for itself.EnergyThe capacity to do work or to make a change in the location, temperature, or structure of matter. Does not have mass and it does not take up space, but it can be measured in terms of what it does.GrowthAn increase in size.DevelopmentStructure and function change in an orderly way as an organism passes through its life cycle. An individual's pattern of _______ is partly determined by genetic instructions.ReproductionOccurs when an individual organism passes on its genetic information to a newly independent organism, or offspring.EvolutionA scientific theory that explains how and why life changes over time. Provides the explanation for why all living organisms share profound similarities, and yet, the life forms on our planet are so incredibly diverse.Natural SelectionIndividuals are always a bit different from their parents and from each other, partly because of changes to their genes. These differences may be helpful or harmful to the individuals that inherit them. In nature, individuals often have very low odds of surviving to reproduce. Individuals with slightly harmful or even average characteristics might be less likely to make it, and those with traits that fit in very well with the local habitat will have the greatest chance to survive and reproduce.This sorting process goes on generation after generation.
