Saprotrophic nutrition
excrete / absorb / digestive / nutrients / heterotrophic / waste
- Fungi feed by a special type of nutrition called 'saprotrophic' nutrition.
- First, they secrete enzymes out of their body, onto the food.
- These break down and digest the food.
- They then the small into their cells.
