Which kingdom includes organisms that decompose dead organic matter?

• A. Fungi
• B. Plants
• C. Animals
• D. Producers

Answer: (A)

Decomposition and nutrient recycling rely on organisms that break down dead matter. Fungi are the kingdom known for this job because they release enzymes outside their cells to digest complex organic material—like wood, leaves, and other detritus—and then absorb the resulting nutrients. This saprotrophic lifestyle makes fungi essential recyclers in ecosystems, turning dead material back into usable nutrients for other organisms. Plants, as producers, create their own energy-rich compounds from sunlight, while animals are consumers that obtain energy by eating other organisms. The decomposer role is a distinctive function of fungi, which is why they’re the ones included in this question. Examples you might recognize include mushrooms, molds, and yeasts.
