Question

What plants would cease to exist without insects or birds to spread their pollen/seeds.?

Answer 1

all angiosperm, or flowering plants... but we as animals can polinate too. all food but grasses would not exist. I.e. corn, wheat, rice... but nothing would be around to eat it.

Answer 2

Angiosperms and Gymnosperms which requires pollinators to scatter the seeds/pollens away may have never existed. Insects/birds and these plants are coexisting to each other, without them, there are no seeds and nectar for food.

However, there are also possible pollinators like wind and water. But mostly animals are the most contributors.
