I've never heard of a seed-eating bird... but if there is such a thing then yes, they would be a consumer.
no, it is a consumer. Producers produce (make their own) food. Plants are producers
they eat worms
Considering that the name is "seed-eating", the birds eat seeds, not trees.
worms
Primary consumer

There are some seed eating birds that feed at different times to avoid competition. Others do it to avoid conflict from other birds, and some eat with other birds.
A bird is a herbivore! * Some birds eat insects. I think birds are omnivores. So if the bird eats vegetation they are primary consumers if they eat animal food (insects, meat) they are secondary consumers.
There are many from plant eaters like cattle and rabbits. Fruit eaters and seed eaters like birds and chipmunks. Including meat eaters like humans, wolves and hawks.
Birds of prey, like Hawks are the main predators of Insect eating Birds. For example the Eurasian Sparrow hawk is the main predator of the Blue tit, Great tit, Wren, Eurasian Robin and Eurasian starling which are all Insect eating Birds.
Yes because they don't know how to hunt so if there was no more seed for them to eat then they would die because they don't know how to hunt
Could be for a variety of reasons, but grasping a tree bark or the seed itself could be some of them. Could be evolutionarily vestigial as well, like wings on ostriches.
Sparrows (several species worldwide) are mainly seed eating birds, with short strong beaks. During Summer, they will eat insects to feed to their young.
Amongst bird-keepers - seedeaters. Otherwise, there is no name that describes them all beyond the scientific name for seedeater - granivorous.
