Biological Classification Levels Notes

Organisms interact with the nonliving (abiotic) parts of the
environment in many ways.
So how is a Biome different from an Ecosystem or a Habitat?
Habitat: the area or environment where an organism or
ecological community normally lives or occurs.
An Ecosystem: a system formed by the interaction of a
community of organisms with their physical environment. It
includes many habitats and living and non-living things.
A Biome is a major regional grouping with similar climate,
plants, and animals.
Organism or
Individual: A
single living thing
– Oxygen
Biomes are made up of several ecosystems
– Temperature
Biome: large areas on the earth with similar
climate, plants, and animals.
– Soil
Ecosystem: The community of species that live in an
area, along with the abiotic factors in the area
– Sunlight
Community: All the different
species that live together in an area
Abiotic factors are the nonliving parts of a habitat.
My Family
Population: A group of
organisms of the same species
living in a particular area
Biotic factors are the living or once living parts of a habitat.
Another Way to look at it:
There are 2 parts to a habitat:
Habitat is an environment that provides the things an
organism needs to live, grow, and reproduce.
