Question

Who is responsible for converting complex organic substances into simple inorganic substances in an ecosystem?

• A. Producer
• B. Primary consumer
• C. Secondary consumer
• D. Decomposer

Answer 1

The correct option is D Decomposer

• Decomposers like microorganisms break down dead and decaying organic matter into simpler components.
• During decomposition, organic substances like carbohydrates, proteins, and lipids from dead bodies of plants and animals are converted into inorganic substances like hydrogen, oxygen, calcium, iron, and sodium.
• These inorganic substances are released back into the soil and they serve as nutrients for the growth of plants. Without decomposers, nutrients won't be recycled and the ecosystem will get unbalanced.
