ECOLOGY
Ecology
• The study of how organisms
interact with their
environment
• All organisms must interact
with both living (Biotic) and
the nonliving (Abiotic) things
that surround them
Ecology-Abiotic Factors
• Abiotic-are non-living things that are part of the environment that
affects living organisms and the ecosystems.
• Examples: Soil-water-air-temperature-sunlight-wind-weatherlandforms-lightening-etc…….
Ecology-Biotic Factors
• Biotic- a living thing, as an animal or plant, that influences or affects
an ecosystem.
• Examples-producers-consumers-decomposers-plants-animals-leavesetc….
Abiotic and Biotic Factors
Organism
• an individual animal, plant, or single-celled life form
• Only one type
Population
• all the inhabitants of a particular town, area, or country
• the body of inhabitants of a place
Community
• An ecological unit composed of a group of organisms or a population
of different species occupying a particular area, usually interacting
with each other and their environment.
Ecosystem
• A system that includes all living organisms (biotic factors) in an area as
well as its physical environment (abiotic factors) functioning together
as a unit. Supplement. An ecosystem is made up of plants, animals,
microorganisms, soil, rocks, minerals, water sources and the local
atmosphere interacting with one another
Biomes
• A major ecological community of organisms adapted to a particular
climatic or environmental condition on a large geographic area in
which they occur. Supplement. Biomes may be classified into:
Terrestrial biomes or land biomes - ex. tundra, taiga, grasslands,
savannas, deserts, tropical forests, etc.
Biosphere
• the global ecological system integrating all living beings and their
relationships, including their interaction with the elements of the
lithosphere, geosphere, hydrosphere, and atmosphere.
Levels of Organization
• Cells – tissues – organs – organ systems – organisms – population –
community – ecosystem – biosphere
