🍂 Nature's Recycling Team

Imagine if nothing ever rotted — we'd be buried under mountains of dead leaves, animals, and waste! Thankfully, decomposers (bacteria and fungi) are constantly at work, breaking down dead material into simple nutrients that plants can reuse. They're the ultimate recyclers, and without them, life would grind to a halt.

Quick Recall Flashcards

What is decomposition and who carries it out?
Decomposition is the breakdown of dead organisms and waste into simpler substances. Carried out by decomposers: mainly bacteria and fungi. This releases nutrients back into the soil for plants to use.
How do decomposers feed? (saprotrophic nutrition)
Decomposers use saprotrophic nutrition: 1. Secrete enzymes onto dead material (extracellular digestion) 2. Enzymes break down large molecules 3. Decomposer absorbs the small soluble products
