Which of the following statement are incorrect?

#Unit 10. Ecological Principles
  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

#Unit 6. System Physiology – Plant

Plant and fungal plasma membrane H+-ATPases and Ca2+-ATPases are members of a class known as P-type ATPases, which are phosphorylated as part of the catalytic cycle that hydrolyzes ATP. Because of this phosphorylation step, the plasma membrane ATPases are strongly inhibited by

#Unit 4. Cell Communication and Cell Signaling

In bone marrow, stem cells are committed to different lineages. Factors that stimulate colonies of these different lineages are interleukin-3 (multi-CSF), IL-7,  granulocyte- macrophage colony stimulating factor (GM-CSF) and granulocyte or macrophage colony- stimulating factor (G-CSF or M-CSF). In a mouse deficient in IL-7 the number of which cells will not be altered
