I am slightly confused by this question. I have narrowed it down to two possibilities however. Could you explain why one is correct.

 

Which of the following describes animals best

 

a) Multicellular, heterotrophic, usually motile

b) eukaryotic, invertebrates or vertrebrates and feeds on other organisms

I would pick option b

Thank you for your help!

I agree with foodchain; probably B.

Thank you. Is there any particular reason for this?

A is too non-specific.

B covers more 'ground' so to speak.

 

Do you see what I mean?

Thank you. Is there any particular reason for this?

 

Multicellular can apply to more then just animals, plus I do not think 100% of animals are multicellular. Motility can apply to so much its not even funny, so its far not an specific animal trait. Heterotroph can apply to animal, and I think all animals are heterotrophs, though I am not fluent in all the trophs, I know they surely are not auto or photo at least. All animals are eukaryotic, but so again are so many other forms of life. Invertebrate to vertebrate surely speaks of animals though and of course again I think all animals do indeed feed on other organisms.
