Biotic and Abiotic Factors
Unit 3 : Chapter 15 : Section 1
Levels of Organization Among Living Things
The environment is organized into 5 levels.1. Organism2. Population3. Community4. Ecosystem5. Biosphere
Levels of Organization
• One indivual organism – ONE living thins
• Ex. a moose -
Unit 3 : Chapter 15 : Section 1
Organization of the Environment
Population• Populations – All members of 1 species in a particular area
– groups of individuals of the same species that live together in the same area at the same time.
Levels of Organization
• Population- groups of individuals that belong to the species and live in the same area. (living-living same species)
• Ex many moose
Unit 3 : Chapter 15 : Section 1
Organization of the Environment
Communities• Communities are – Different populations in one area
– made up of all of the populations of different species that live and interact in an area.
Levels of Organization
• Community- groups of different populations (more than one population or different groups of species)
Ex many groups of moose beavers, trees, grass (all living)
Unit 3 : Chapter 15 : Section 1
Organization of the Environment
Ecosystems• Ecosystems are made up of abiotic and biotic factors
in a particular area
Habitat – place where an org. can live, grow and reproduce Niche – the role an org.
occupies and the function it performs (eat, prey/predator, etc)
Levels of Organization
• Ecosystem- all organisms in a particular area along with the nonliving. (living and nonliving)
Ex many groups of moose beavers, trees, grass, rocks, water, mountains
Levels of Organization
• Biome- group of ecosystems that have the same climate and similar dominant communities
• Biomes: tropical rain forest, tropical dry forest, tropical savannah, temperate grassland, desert, temperate woodland and shrubland, temperate forest, northwestern coniferous forest, boreal forest (taiga), tundra, mountains and ice caps
Unit 3 : Chapter 15 : Section 1
Organization of the Environment
Biosphere• A biosphere contains the whole area of the Earth
where life exists, including its abiotic factors.
Levels of Organization
• Biosphere- all of the planet where life exhists, includes land, water, and, air
• Life extends 8 km up and 11 km below the surface
