Humans Energy Trophic Levels Consumer Describe Manipulated Transfer

Humans manipulate energy transfer by creating simple food chains (3-2 trophic levels) in agriculture, e.g., eating livestock that consumed producers, to maximize energy transfer into consumed biomass.

Gli esseri umani manipolano il trasferimento di energia creando catene alimentari semplici (3-2 livelli trofici) in agricoltura, ad esempio mangiando bestiame che ha consumato produttori, per massimizzare il trasferimento di energia in biomassa consumata.

Front Describe how humans have manipulated energy transfer through trophic levels in the farming of plants and animals to our advantage.
Back Human manipulation of biomass:
  • Agriculture results in simple food chain of 3 or 2 trophic levels
  • Animal feed (producer) -> Livestock (primary consumer) -> Humans (secondary consumer)
  • Minimal energy is lost bc fewer trophic levels - as much energy as possible transferred into biomass eaten by humans
