Did animals appear before plants, or vice versa? Were the first organisms animals or plants?

The first organisms were bacteria. Only after Eukaryotic cells evolved (about 2 billion years after the beginning of life) and then multicellular organisms arose (another billion years later) did organisms diverge into plants, animals and fungi (the three major kingdoms of eukaryotic life)

The first "organisms" were heterotrophs; some people might call them animals, but real animals were a few billion years in thr future. It was after complex "food" molecules became scarce that photosynthesis (the first "plants?") evolved.

well i think that unicellular organisms appeared first .
first prokaryotes & then eukaryotes.
and then the evolution took place & both the kingdom animalia and plant evolved side by side.

plants first, then animals and the animals thus had food to get life from.
