6 Levels of Organization in Ecology
Scientists Study Ecology on 6 Different Levels

In ecology, there are 6 levels of organization.  Each of level is listed below, from the smallest to the biggest:
(1) Organism     ⇒     (2) Population          (3) Community   
(4) Ecosystem          (5) Biome              (6) Biosphere

Next Generation Science Standards:

MS-LS2-1. Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.

MS-LS2-2. Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.

MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

MS-LS2-5. Evaluate competing design solutions for maintaining biodiversity and ecosystem services.*

HS-LS2-2. Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.

HS-LS2-6. Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem. (Self Note: Changes in an Ecosystem / Succession)

HS-LS2-8. Evaluate the evidence for the role of group behavior on individual and species’ chances to survive and reproduce.

Additional Information


There are *many different types of biomes and each occupies a specific latitude on the earth’s map.  For example, the tropical rain forest biome occupies near the earth’s equator, while the tundra biome occupies near the earth’s polar regions.
*Most scientists agree that there are 14 different types of biomes.  Some examples of these biomes are: tundra, rainforest, marine, estuaries…etc.
