both organisms benefit
(ex. lichen (algae + fungus)) |
|
|
Symbiosis
|
A close association between organisms of two or more species
Commensalism Mutualism Parasitism |
|
|
Energy Flow

tracing energy as it moves from one organism to next levels of energy flow (Trophic Levels)
|
|
|
Producers
|
turn energy into useful forms (potential energy)
|
|
|
Gross Primary Productivity
