[4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The bee hummingbird (Mellisuga helenae) – the world's smallest bird – evolved to dwarfism likely because it had to compete with long-billed hummingbirds having an advantage for nectar foraging from specialized flowers, consequently leading the bee hummingbird to more successfully compete for flower foraging against insects.

There are certain primary consumers that are called specialists because they only eat one type of producers.

A hummingbird's kidneys are capable of rapidly producing large quantities of hyposmotic urine i.e. urine containing a lower concentration of dissolved substances than the blood. [14] Some other bird groups have one or more similar specializations – for instance, the Lories , one group of Australasian parrots within the larger parrot family ...
