Explanation:

Spriulina represents a biomass of cyanobacteria (blue-green algae) that can be consumed by humans and other animals.
As an ecologically-sound, nutrient-rich, dietary supplement, spirulina is being investigated to address food security, malnutrition, and as dietary support in long-term space flight or Mars missions.
Its interest for food security is for lower land and water needs to produce protein and energy than required for livestock as meat sources.
Dried spirulina contains 5% water, 24% carbohydrates, 8% fat, and about 60% (51–71%) protein (table). It is a complete protein source, containing all essential amino acids
