Terrestrial vs Aquatic food production systems

We have already discussed these two. Let’s continue the roll and compare directly one and another.

Terrestrial

  • First levels are more energetically efficient
  • Solar energy capture (GPP) more efficient
  • Energy transfer between trophic levels not as efficient

Aquatic

  • Food is harvested from the top trophic levels, such it lacks from energy

 

  • GPP is lower because of the water barrier

  • The transfer between trophic levels is most efficient.
