The consumer species found in lentic habitats include worms, snails, amphibians, crustaceans, insects, reptiles, fish, and birds. Herbivorous groups such as snails, amphibian larvae, and crustaceans play an important role in controlling primary productivity and algal blooms.
What is the role of microscopic organisms in the pond ecosystem?Microorganisms have major roles in pond culture, particularly with respect to productivity, nutrient cycling, the nutrition of the cultured animals, water quality, disease control and environmental impact of the effluent.
