Identify an example of decomposers that are found in the bottom of a pond.

The correct answer is Flagellates.Key Points

• Flagellates are found in the bottom of a pond.
  • They are an example of Protozoa.
  • Protozoa are found in soil, freshwater, and seawater.
  • Some are found in the body of other organisms and are pathogenic. These are unicellular organisms with eukaryotic cells.
  • There is great variation in cell structure, organs of locomotion and modes of nutrition among protozoa.
  • These organisms reproduce by simple cell division.

Additional Information

• Zooplankton is present on the second trophic level in a food chain in the aquatic ecosystem.
• They are primary consumers as they eat phytoplankton (producers) and are themselves in turn eaten by small fishes (secondary consumers).
• Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria.
