Organisms

Water is such a complex and dynamic environment that can host a wide variety of organisms, ranging from microorganisms to larger aquatic creatures. The composition or organisms in water can vary greatly based on factors such as water type (freshwater or marine water), habitat (rivers, lakes, oceans, wetlands), and geographical location. Microorganisms such as bacteria are single celled organisms which are abundant in water and play essential roles in nutrient cycling and decomposition, viruses, which can be infectious agents and pose health risks to humans and algae which are photosynthetic microorganisms that can thrive in aquatic environments, from tiny phytoplankton to larger macroalgae. Protozoa such as amoebas, ciliates and flagellates, Invertebrates such as insets, crustaceans and mollusks, Fish from various freshwater rivers, lakes and ponds, including marine fish from the ocean, plants such as submerged, emergent and floating plantation, microscopic life such as plankton and zooplankton and various aquatic birds, waterfowl, marine mammals and mammals. These organisms collectively form intricate ecosystems that play vital roles in nutrient cycling, oxygen production, and overall ecosystem health.
