Question

b) Why should we use submerged hydrophytes like Elodea or Hydrilla?​

Answer 1

Answer:

Hydrilla (Hydrilla verticillata) and Brazilian elodea (Egeria densa) are both submerged, rooted, freshwater aquatic plants that survive well in up to six meters of water. ... In both species, plant fragments have the ability to take root and grow into new plants, allowing them to spread quickly.
