  • Herbivore: An organism that only eats plants.
  • Pelagic: Relating to the open ocean.
  • Photosynthesis: The process of turning the sun’s energy into sugar as done by plants.

  • Scavenger: an organism that mostly consumes decaying biomass, such as meat or rotting plant material.
  • Trophic level: The position of an or¬ganism in a food web, based on its distance from primary production.
  • Zooplankton: Primary consumers in marine food webs. Small animals that graze on phytoplankton.
