Question

how does microorganisms affects the ecosystem of the body of water?​

Answer 1

Answer:

• Microorganisms especially bacteria are present in all regions of lake/pond ecosystem. Lake microorganisms participate in various biogeochemical cycles, such as decomposing organic material into nutrients as food for other organisms and control the water quality in lakes.
• Freshwater ecosystems contain a great diversity of microbes, including bacteria, archaea, fungi and protists. Bacteria play an important role in breaking down leaves into smaller, dissolved organic matter (DOM).
• Microbes are omnipresent in the biosphere, and their presence invariably affects the environment in which they grow. The most significant effect of the microbes on earth is their ability to recycle the primary elements that make up all living systems, especially carbon, oxygen, and nitrogen (N).
• When water activity outside the cell becomes low enough, it causes osmotic stress: the cell cannot take up water and becomes dormant. The microorganisms are not eliminated, they just become unable to grow enough to cause infection.
• Certain bacteria can break down toxic pollutants. Bacteria help degrade dead animals and plants and bring valuable nutrients back to Earth. Some species also help clean harmful pollutants out of the environment in a process called bioremediation
