Saprobes

Definition

Saprobes are organisms that obtain nutrients by decomposing dead or decaying organic matter. They play a crucial role in nutrient cycling within ecosystems.

5 Must Know Facts For Your Next Test

1. Saprobes are primarily fungi and bacteria.
2. They produce enzymes to break down complex organic substances into simpler compounds.
3. Saprobic fungi are essential for the decomposition process in forests and other natural environments.
4. Many saprobes form symbiotic relationships with plants, aiding in their nutrient absorption.
5. Saprobes contribute to soil fertility by recycling essential nutrients like nitrogen and carbon.
