5 levels of the Environment
• When talking about Ecology, it is important to arrange the scope of discussion.
• In order to organize our discussion, we classify the environment from the most specific to most broad.
Specific: The Organism
When talking about the organism, we are talking about a SINGLE animal, plant, or other organism. It is a biotic factor of the environment.
Population
• Population: group of individuals belonging to the same species that inhabit a specific geographic location at a specific point in time
Ecosystem
• The ecosystem is the community of biotic factors AND all the abiotic factors of the area.
Biosphere
• The biosphere is the part of Earth where life exists. The biosphere is another way to refer to the Earth.
BIOTIC FACTORS• Biotic Factors
Biotic factors are living factors. Anything living OR THAT WAS ONCE LIVING is considered a biotic factor.
Examples of Biotic Factors
• Plants• Animals• Fungi (like
mushrooms)• Protist (like
paramecium, amoeba, and euglena)
• Bacteria
ABIOTIC FACTORS• Abiotic Factors
Abiotic, meaning not alive, are nonliving factors that affect living organisms.
For example, if the temperature drastically changes in an area, it will impact the plants and animals
that can live there.
