Levels of Organization
A group of organisms that belong to the same species and live in the same area
Population

Ecology
Clownfish and the sea anemone have this type of symbiotic relationship.
Mutualistic
Where does all energy in a food web come from?
The Sun
This is a non-native organism that lacks competitors and can disrupt an ecosystem.

Habitat
A symbiotic relationship where one organism benefits and the other organism is harmed
Parasitism

Food Web

Populations of different species that live in the same area and interact with each other
Community

Niche
A symbiotic relationship where one organism benefits and the other is not affected
Commensalism
What does “trophic” mean?

Ecosystem
These are parts of the environment that are not living
Abiotic
A relationship between different species
Symbiosis
This is the general term for any organism that has to eat something else to get its energy
heterotroph
How are food webs and food chains different?
Food webs show all directions of energy flow, a food chain follows one line of energy flow.
