What type of invertebrate are robber crabs? why do these crabs fit in this category? use evidence from the video in your answer.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
