The correct sequence of plants in a hydrosere is:

Options

  1. AVolvox → Hydrilla → Pistia → Scirpus → Lantana → Oak
  2. BPistia → Volvox → Scirpus → Hydrilla → Oak → Lantana
  3. COak → Lantana → Volvox → Hydrilla → Pistia → Scirpus
  4. DOak → Lantana → Scirpus → Pistia → Hydrilla → Volvox

Correct answer

A. Volvox → Hydrilla → Pistia → Scirpus → Lantana → Oak

Step-by-step solution

The correct sequence of plants in a hydrosere is Volvox, Hydrilla, Pistia, Scirpus, Lantana and Oak . A hydrosere is a plant succession which occurs in a freshwater lake. In time, an area of open freshwater such as a lake will naturally dry out, ultimately becoming woodland. During this change, a range of different land types such as swamp and marsh will succeed each other. The succession from open water to climax woodland is likely to take at least two hundred years.
