Description: An aquatic ecosystem is a biological system that develops in a body of water, whether freshwater, saltwater, or brackish. This type of ecosystem includes a variety of living organisms, such as plants, animals, bacteria, and fungi, that interact with each other and their physical environment. Aquatic ecosystems are characterized by their biological diversity and their ability to sustain life under conditions that range from the calm waters of lakes and rivers to the dynamic and complex interactions of oceans. Sunlight, temperature, salinity, and nutrient availability are key factors influencing the structure and function of these ecosystems. Additionally, aquatic ecosystems are essential for the water cycle, climate regulation, and the provision of natural resources. Their health and balance are crucial for global biodiversity and human well-being, as they provide habitats, food, and vital ecosystem services. The conservation of these ecosystems is critical, given that they face threats such as pollution, climate change, and resource overexploitation, which endanger both the species that inhabit them and the human communities that depend on them.
