Document Summary
Lecture 3 background ecology ecosystems and energy flow. Relationships such as competition or mutualism symbiotic relationships. Look at organisms and how they interact with their surroundings (abiotic factors: soil, water, etc. Niche a job or role a species play in its habitat. Ex: clownfish coral reef (habitat) cleans the anemone from floating debris: anemone provides the clownfish with a home and protects it from surrounding predators. If it does not play a role, then another species will come along and do the job. Therefore, size is not a clue in what defines an ecosystem.

Complex ecological systems are studied at several levels. Starts with the individual into the really complex layer of life on this earth.
