+## Nutrient Recycling
+- There is a `limited` amount of `nutrients` on earth
+    - e.g. you are probably aware of the water cycle – where water is
+    constantly being `recycled` in nature.
+    - There are similar cycles for all nutrients.
+- When plants and animals die, their nutrient content is `not wasted`.
+- Bacteria and fungi decompose the remains and release the nutrients back into the abiotic environment (i.e. into the soil, nearby water and air).

 ## Benefits of Succession
 - Provides a mechanism by which ecosysmtems maintain their long term sustainability.
 - Allows ecosystems to recover from natural or human caused distrubances.
