#Part-B Specialized Branches in Biotechnology
  1. Productivity/Biomass ratios in aquatic ecosystem are higher and energy transfer rates to higher trophic levels are faster than terrestrial ecosystem
  2. In aquatic ecosystems most plant and algal biomass can be consumed by herbivores than herbivore of terrestrial ecosystem
  3. Assimilation efficiencies for herbivores average only about 5–20% and are lower because even plant leaves have many indigestible cell walls
  4. Invertebrates tend to have higher production efficiencies than vertebrates, because they devote more energy to sustaining their metabolism
