I want to know the answer to the following question:
What portion of the biosphere would be devastated absent the complex pollination role of insects?
All the background I'm provided with is that "Insect pollinators are essential to the life-cycle of many flowering plant species on which most organisms, including humans, are at least partly dependent; without them, the terrestrial portion of the biosphere (including humans) would be devastated.". Is that enough to answer the question?
Answer: yes
