Pond becomes a meadow as a result from the process of natural eutrophication.
What is eutrophication?
- "Eutrophication is the gradual enrichment of a body of water, or parts of it, with minerals and nutrients, mainly nitrogen and phosphorus, resulting in abundant growth of simple plant life."
- Excessive plant production, damaging algae blooms, a rise in the frequency of anoxic occurrences, and fish fatalities are all consequences of eutrophication.
What is a meadow?
- "It is a piece of low ground near a river."
Layers of detritus accumulate when pond plants develop, die, and disintegrate and there is an increase in the level of nutrients. Over time, these layers of decaying debris rise the pond floor. The pond floor eventually gets near enough to the bottom that emergents can grow all the way across it. The ponds develop marsh meadows as a result of this.
Hence, the correct option is A. Pond becomes a meadow.
