Biological Levels in Biology: The World Tour
Whether Bacterium, Fungus, Protist, or Animal, if it’s alive it is made of one or more cells.
Cells are the first level (the most basic living level).
⬇
Cells can become tissue.
⬇
Tissues make organs (although organs are not always made up of tissue). The heart is an organ.
⬇
Organ systems: comprised of many different organs. For example, the colon and small intestine are part of the Digestive System. The Digestive System is an Organ System.
⬇
Organisms: all life forms such as humans, animals, fungi, etc…
⬇
Population: a type of life form breeds to become a population.
⬇
Community: different populations living together.
⬇
Ecosystem: a biological community of interacting organisms and their physical environment.
⬇
Biome: categories of ecosystems found in different locations. For example, a desert biome or a rainforest biome.
⬇
Biosphere: the sum of all biomes; all the areas where organisms live.
Definitions:
Abiotic: A means without and BIO means life: without life, non-living. For example, a rock is considered non-living because it doesn’t have any cells.
