• Ecology is the study of the relationships between the natural world and all the living and non-living things in that environment
Levels of organization in Ecology
• Biosphere• Ecosystem• Community• Population• Individual
(species)
SPECIES
• Similar organisms that can successfully reproduce among themselves in their natural environment– THIS MEANS: they
produce offspring that can reproduce as well
Examples: Species of frog: water frog, red-eyed tree frog
• Species of horse: Clydesdale horses, Andalusian horses
POPULATION
• A population is made of many of the SAME KIND of species that live in the same area– Compete with each other for food, mates, water and space
Examples• Population of trout in a river• Population of bats living in a cave• Population of GI students in the
classroom
COMMUNITY
• A community is made of many groups of populations that interact in an area
Examples:• A forest: populations of trees,
populations of mushrooms, populations of birds
• A lake: populations of insects, populations of fish, populations of algae
ECOSYSTEM• An ecosystem includes all
the living organisms in an area and all the non- living things that affect it
Examples:• Forest ecosystem
includes grass, soil, wind, sunlight, animals
• Ocean ecosystem includes fish, coral, rocks at the bottom, temperature of water
BIOSPHERE
• The part of the Earth that supports all organisms, made up of all of the Earth’s ecosystems
Examples:• Made up of the water,
land, living things and air
Levels of Organization
Biosphere
Ecosystem
Community
Population

• SJ: Why do you think the ecological model (in the note today) is a picture of circles within circles?
