Which of the following organisms is a decomposer in an ecosystem? MCQ with Answer and Explanation

Fungi (and bacteria) are decomposers that break down dead organic matter and waste, releasing nutrients back into the ecosystem. They are saprotrophs. Grass is a producer, lion and eagle are consumers (carnivores). Decomposers are essential for nutrient cycling, especially carbon and nitrogen cycles. Without decomposers, ecosystems would be clogged with dead material.
