Question

What are decomposers?

• A. Decomposers break down the complex organic substances of garbage, dead animals and plants into simpler inorganic substances.
• B. Decomposers synthesise the complex organic substances of garbage, dead animals and plants into simpler inorganic substances.
• C. Decomposers break down the complex inorganic substances of garbage, dead animals and plants into simpler inorganic substances.
• D. Decomposers break down the complex organic substances of garbage, dead animals and plants into simpler organic substances.

Answer 1

The correct option is A Decomposers break down the complex organic substances of garbage, dead animals and plants into simpler inorganic substances.

Decomposers are organisms that break down dead or decaying organisms and in doing so, carry out the natural process of decomposition. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development.

Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients and dead matter and waste would pile up.

Therefore, the correct answer is option A.
