  • It is the layer where the sunlight can easily penetrate.
  • The photosynthesis process is driven out extensively by the aquatic plants existing in this layer.
  • The primary producers are present in this zone that provides the food to almost all the freshwater organisms.
  • In this zone, the rate of respiration is equal to the rate of photosynthesis.
