Water ecosystems are environments where water is the primary medium for life. They include various types such as lakes, rivers, ponds, and wetlands. These ecosystems support a diverse range of organisms, including fish, amphibians, invertebrates, and aquatic plants. The health of these ecosystems is crucial for maintaining biodiversity and providing resources like clean water. In water ecosystems, interactions between organisms and their environment are vital. Producers, such as algae and water plants, convert sunlight into energy, forming the base of the food web. Consumers, including herbivores and carnivores, rely on these producers for sustenance. Additionally, decomposers break down organic matter, recycling nutrients back into the ecosystem.
