Identify the decomposer of an aquatic ecosystem.

The correct answer is: Bacteria

• Decomposers are microorganisms that act on dead and decaying organic materials.
• Decomposers include bacteria, fungi, which are also called as saprophytic organisms.
• They clear the ecosystem from the dead materials, releasing the nutrients from the dead materials back to the nutrient cycle.
• Algae, phytoplankton and aquatic plants are included under producers, as they contain chlorophyll.
