trophic
(adjective)
 Describing the relationships between the feeding habits of organisms in a food chain.
Examples of trophic in the following topics:
- 
Planktonic Food Webs- However, determining the trophic level of some plankton is not straightforward.
- As these organisms form the base of the marine food web, this variability in phytoplankton growth influences higher trophic levels.
 
- 
Organization of Ecosystems- All life forms in an ecosystem can be broadly grouped into one of two categories (called trophic levels):
- In general, trophic levels are used to describe the way in which a particular organism within an ecosystem gets its food.
 
- 
Planktonic Communities- Plankton are primarily divided into broad functional (or trophic level) groups: Phytoplankton , Zooplankton, and Bacterioplankton.
- However, determining the trophic level of some plankton is not straightforward.
- As these organisms form the base of the marine food web, this variability in phytoplankton growth influences higher trophic levels.
 
- 
Chemoautotrophs and Chemoheterotrophs
- 
Hydrothermal Vent Microbial Ecosystems- The chemosynthetic bacteria grow into a thick mat, covering the hydrothermal vent, and this is the first trophic level of the ecosystem.
 
- 
Nongenetic Categories for Medicine and Ecology- In ecology, microorganisms are classified by the type of habitat they require, or trophic level, energy source and carbon source.
