1. Fungi: A classic example! Fungi like mushrooms, molds, and yeasts break down dead organic matter like fallen leaves, wood, and animal carcasses. They release enzymes that digest the material, absorbing the nutrients.
2. Bacteria: Many bacteria, like those found in soil, decompose dead plants and animals. These bacteria are crucial for recycling nutrients back into the ecosystem.
3. Earthworms: While not strictly microscopic, earthworms are also saprotrophs. They consume decaying plant matter and soil, breaking it down and enriching the soil with their castings (poop!). They play a vital role in soil health and nutrient cycling.
