Answer 1

I'm not sure what your asking but you seemed to have already answered. 1 plant, a cabbage, 2 insects that feeds on live plant tissue, the caterpillar and greenfly (aphid). Caterpillar is metamorphosed to a butterfly and lay caterpillar eggs while the aphid is a sucker insect living on vascular plant fluids. The snail feeds on dead cabbage leaf. Ladybird, or lady bug feeds on the aphids as do the young. Thrushes eat all the snails and insects, the bird manure returned to the soil, as does the insect waste. Sparrow hawk will prey on the thrush and so you have a food chain or your food web. I do not know what your reference to blue something is, but you can find it's niche.
