What is Ecology?
Ecology is the study of the interactions of living organisms with one another and with their environment
Ecology – Levels of Organization The study of ecology ranges from the study of a single organism to the entire biosphere.
Organism An individual form of life that has the ability to act or function independently.
Population A group of organisms of the same species (a group of organisms that can breed) that live in a specific geographical area.
Community A group of different populations that live together in a defined area.
Ecosystem A collection of all the organisms that live in a particular place with their physical environment.
Biome A large region characterized by a specific climate and certain kinds of plants and animal communities.
Biosphere The part of Earth in which life exists including land, water, and the atmosphere.
Factors That Affect Population Size
Abiotic Factors -nonliving factors that affect population size Examples would be weather and climate
Biotic Factors -a factor that is related to the activities of living things Examples would be food, such as grass or other animals
Habitat vs Niche
A habitat is a place where an organism usually lives.
A niche is the unique position occupied by a species, both in terms of its physical use of its habitat and its function in an ecological community.
The Abiotic and Biotic Environment EQ: How can we classify the levels of ecological organization?

Life Science Ecology & the Environment. Ecology Study of the interactions that take place among organisms and their environment.
Today I will study the components of an ecosystem because I need to understand how living things depend on one another.
