  • Biomass consists of tissue from living or recently deceased organisms.
  • Biomass originates from photosynthetic organisms like green plants and algae.
  • These organisms produce biomass by converting energy from sunlight during photosynthesis.
  • Biomass production involves the creation of glucose through photosynthesis.
  • The glucose produced is stored in plants, evident in the sweetness of fruits like blackberries.
  • Biomass is also generated through the synthesis of various molecules in both plants and animals.
  • Animals, such as caterpillars, synthesize proteins from ingested materials.
  • Plants use absorbed materials to create substances like lignin, which forms wood.
  • Understanding these processes helps in making connections across different topics in the curriculum.
