aquatic food web

An aquatic food web describes the complex network of interactions among organisms in water ecosystems, such as oceans, lakes, and rivers. It begins with producers like phytoplankton and aquatic plants that use sunlight to create energy through photosynthesis. These serve as food for primary consumers, such as small fish and zooplankton. Bigger fish and predators, like sharks or dolphins, are secondary consumers. Decomposers, like bacteria and fungi, break down dead organisms, recycling nutrients back into the ecosystem. This interconnected system illustrates how energy flows and how species depend on each other for survival.
