Chemoautotrophs

Key concepts to establish:

• Students already know that autotrophs synthesise carbon compounds from inorganic sources (2.2.21)
• This section distinguishes between TWO types of autotrophs based on their energy source
• Photoautotrophs use light energy (photosynthesis)
• Chemoautotrophs use energy from exothermic inorganic chemical reactions (chemosynthesis)

Example ecosystems powered by chemosynthesis:

• Hydrothermal vents (deep ocean, 2000-4000m depth)
• Whale falls
