if the multicellular organisms arise from the unicellular brainly

You come to the right conclusion, but through the wrong path.Yes, all species are related.But not because multicellular organisms come from unicellular organisms (which they do).

You come to the right conclusion, but through the wrong path.Yes, all species are related.But not because multicellular organisms come from unicellular organisms (which they do).We know all species, both of multicellular and unicellular organisms, are related because we can trace their ancestry through DNA to a common ancestor.

If you only considered eukaryotes, you would end up with a common ancestor that predates the development of photosynthetic eukaryotes, and many (most?) of its extant descendants would be still unicellular.
