Octopus and squid have little suction cups on their tentacles. It helps with sticking onto food (so it doesn't get away) and also helps with sticking into things. If it wanted to camouflage into some rocks, it can use its tentacles to cling to to the rock.
Tentacles can also grab and carry things. Scientists have made tests where they would put a clam in a jar with the lid screwed on. The octopus would grab onto the jar and use its tentacles to twist the lid off.
Without tentacles, octopuses and squids would be pretty helpless and probably couldn't survive in the deep ocean.

Answer: The percentage would be 19%, 51% and 30%.
Explanation:
Since we have given that
Number of food eaten by X = 57
Number of food eaten by Y = 153
Number of food eaten by Z = 90
Total number of food eaten = 
So, Food percentage of flock X = 
Food percentage of flock Y = 
Food percentage of flock Z = 
Hence, the percentage would be 19%, 51% and 30%.
