Organization of Living Things II
Topic (22) Apply statistics about population variation as related to population traits. (HS-LS3-3)
The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
This topic focuses on “population” – (a group of organisms of one species that interbreed and live in the same place at the same time). Variation and distribution of expressed traits in a population can be described through statistics and probability.

Organelle – Definition of organelle. : a specialized cellular part (such as a mitochondrion, chloroplast, or nucleus) that has a specific function and is considered analogous to an organ.
Cells – The basic unit of all living things except viruses. In advanced organisms, cells consist of a nucleus (which contains genetic material), cytoplasm, and organelles, all of which are surrounded by a cell membrane.
Tissues – In biology, tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
Organs – An organ pertains to a group of tissues that perform a specific function or group of functions. … In animals, organs include heart, lungs, brain, eye, stomach, spleen, bones, pancreas, kidneys, liver, intestines, skin, urinary bladder and sex organs.
Organ systems – In biology, an organ system is a group of organs that work together to perform one or more functions. Each does a particular job in the body, and is made up of certain tissues.
Organisms – An individual living thing that can react to stimuli, reproduce, grow, and maintain homeostasis. Supplement. An organism refers to any individual living thing that can react to stimuli, reproduce, grow, and maintain homeostasis.
Populations – A group of organisms of one species that interbreed and live in the same place at the same time (e.g. deer population) (taxonomy) A low-level taxonomic rank. (statistics) A set of individuals, objects, or data from where a statistical sample can be drawn.
Communities – Community, also called biological community, in biology, an interacting group of various species in a common location. For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
Ecosystem – A system that includes all living organisms (biotic factors) in an area as well as its physical environment (abiotic factors) functioning together as a unit. Supplement. An ecosystem is made up of plants, animals, microorganisms, soil, rocks, minerals, water sources and the local atmosphere interacting with one another.
Biosphere – The biosphere is the zone of air, land and water where organisms exist. It is commonly known as the global sum of all ecosystems and consists of several layers including the atmosphere, the lithosphere and the hydrosphere. … And that’s the overlapping areas and regions of these three where you find living organisms.
