Advantages of terrestrial biomes
04/07/2023 26
Advantages
• Clean and eco-friendly energy source.
• Products that are used in biomass are easily available.
• The material for biomass will surely never run out.

04/07/2023 27
Disadvantages of terrestrial biomes
• Costly sometimes (depending on the substrate).• The clearance of large areas including forests.• Releases methane into the air (lesser than fossil fuels).• Sustainable under certain conditions only.• Consumption of fresh water.• Competition for arable land.• Food-fuel debate.

Advantages of macroalgae as a biomass for energy production
• No fresh water required.
• Very abundant.
• Plays an important role in carbon capture and
CO2 storage (0.7 million tons/year).
• Nitrogen and phosphorus are provided by fish.
• Can be collected from industrial waste.
