Interactions in Marine Ecosystems

The rate at which autotrophic organisms produce energy per unit area through photosynthesis or chemosynthesis.

A relationship in which one organism benefits while the other is neither harmed nor benefited.

Mass of living things in a given area

The use of light energy to create glucose from carbon dioxide and water.

A relationship between tow organism where the parasite obtains benefit at the expense of the host

Process by which food in the form of sugar (Glucose) is transformed into energy within cells

6CO2 + 6H20 -> (light) C6H12O6 + 6O2 or Carbon Dioxide + Water -> (light) Glucose + Oxygen

 the rate at which energy is added to the bodies of a group or organism

TLTE= production at present trophic level/production at previous level X 100
