Primary ProductersPrimary Producters
• Capable of using light energy to perform photosynthesis and thus create their own food

Autotrophs & HeterotrophsAutotrophs & Heterotrophs
• Autotroph – organism capable of producing own food
• Heterotroph – organism that needs to ingest nutrients/food

Green algaeGreen algae
• Most found in freshwater or terrestrial environments
• Unicellular
• Bright green because chlorophyll is not masked.
