• Scientists study microplanktons to understand water quality and nutrient cycles in lakes.
• The abundance of microplanktons in the sample indicated a healthy marine environment.
• Microplanktons can be observed only under a microscope due to their tiny size.
• Climate change affects the distribution and composition of microplanktons in polar regions.
